How am I accessing my Dictionary wrong?

So I have been racking my brain on this for a couple of days now and I can't figure it out. It has to be something simple that I'm doing wrong. So in the code below I have a dictionary set up for a prototype of a word game I'm making. It's very simple just both the key and values are a string of the word itself. However no matter what I do the only key that returns true when I look through the dictionary is the very last word in my TextAsset no matter the size or whether or not I use and ordered Dictionary or a regular dictionary. I've gone through a million options but can't figure out how to be able to query my dictionary correctly.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System.Linq;
 using System.Collections.Specialized;
 
 public class DictionaryTest : MonoBehaviour {
 
     //Dictionary<string, string> myDictionary = new Dictionary<string, string>();
     //HashSet<string> myOtherDictionary = new HashSet<string>();
     public string wordToCheck;
     TextAsset myTextAsset;
     //char[] delimeters = { '\r', '\n' };
     List<string> myList = new List<string>();
     //int counter = 0;
     //string myValue;
     OrderedDictionary myOrderedDictionary = new OrderedDictionary();
     ICollection keyCollection;
     ICollection valueCollection;
     int dictionarySize;
 
     
 
     private void Awake()
     {
         myTextAsset = Resources.Load("DictionaryTest", typeof(TextAsset)) as TextAsset;
         foreach (string word in myTextAsset.text.Split('\n'))
         {
             myList.Add(word);
         }
     }
 
 
     // Use this for initialization
     void Start () {
         foreach (string word in myList)
         {
             myOrderedDictionary.Add(word, word);
         }
 
 
 
         //foreach (string word in myTextAsset.text.Split('\n'))
         //{
         //    myOtherDictionary.Add(word);
         //}
         //myDictionary.Clear();
         //myDictionary = myTextAsset.text.Split('\n').ToDictionary(w => w);
         Debug.Log("There are " + myOrderedDictionary.Count + " items in myOrderedDictionary.");
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetMouseButtonDown(0))
         {
             //if (CheckWord(wordToCheck))
             //{
             //    Debug.Log(wordToCheck + " is a valid word");
             //}
 
             //else if(!CheckWord(wordToCheck))
             //{
             //    Debug.Log(wordToCheck + " is NOT a valid word");
             //}
 
             //if (myDictionary.TryGetValue(wordToCheck, out myValue))
             //    {
             //    print(myValue + " exixts");
             //}
 
             //if (myOtherDictionary.Contains(wordToCheck))
             //{
             //    print(wordToCheck + "exists in myOtherDictionary");
             //}
 
             keyCollection = myOrderedDictionary.Keys;
             valueCollection = myOrderedDictionary.Values;
             dictionarySize = myOrderedDictionary.Count;
             PrintContents();
 
             if (myOrderedDictionary.Contains(wordToCheck))
             {
                 print(wordToCheck + " exists in myOrderedDictionary");
             }else if
                 (!myOrderedDictionary.Contains(wordToCheck))
             {
                 print(wordToCheck + " does NOT exist in myOrderedDicionary");
             }
         }
     }
 
     public void PrintContents()
     {
         string[] myKeys = new string[dictionarySize];
         string[] myValues = new string[dictionarySize];
         keyCollection.CopyTo(myKeys, 0);
         valueCollection.CopyTo(myValues, 0);
 
         for (int i = 0; i < dictionarySize; i++)
         {
             print("Key: " + myKeys[i] + "   Value: " + myValues[i]);
         }
     }
 
     //public bool CheckWord(string word)
     //{
     //    return myDictionary.ContainsKey(word);
     //}
 }

As you can see I've been doing a lot of testing so forgive me, and it's also just prototyping code so I haven't been keeping things nice looking or cared about structure.

The last thing I attempted was an Ordered Dictionary using a sorted list and parsing my text asset simply by the '\n' delimeter, and then feeding that into my dictionary. However the outcome was still the same no matter how I created the dictionary.

As you can see the word aalii is showing as nonexistent in my dictionary but it is clearly represented in the list there, whereas aals does exist as the final key/value pair and queries true.

I've checked the text document just in case and it is set up just fine, no extra spaces or unforseen errors in it. I am using Visual Studios to create the text documents but I don't know why that matters. I'm also using Unity 5.6.1f1.
