How to show the instance of a class's variables in the inspector.

Hi, I'm attempting to allow myself to view the variables of one class as an instance in another class. Currently here is what my inspector is showing

This is my stats script( some functions are omitted just to save space):

     using UnityEngine;
     using System.Collections;
     using System;
     
     [Serializable]
     public class Stats : MonoBehaviour {
     
         //Base Stats
         public Character CharacterName;
         public int Strength;
         public int Dexterity;
         public int Intellect;
         public int Mind;
         public int MaxHealth;
         public int Health;
         public int MaxMP;
         public int MP;
         
         //Charater Development
         public int Level;
         public int Experience;
         public int LevelUpExp;
     
     }

And here is my PartyInfo script that has the instance of the Stats class. ( again functions omitted to save space)

 using UnityEngine;
 using System.Collections;
 using System;
 using System.Runtime.Serialization.Formatters.Binary;
 using System.IO;
 
 [Serializable]
 public class PartyInfo : MonoBehaviour {
 
     public static PartyInfo partyInfo;
     public Stats[] characterStats = new Stats[7];
     public Inventory playerInventory;
     public EquipmentInventory[] characterEquipment = new EquipmentInventory[7];    
     
     // Databases
     public ItemDatabase itemDatabase;
     public SkillDatabase skillDatabase;
     
     // Happens before start
     void Awake(){
         // if we don't have a control
         if(partyInfo == null)
         {
             DontDestroyOnLoad(gameObject);
             partyInfo = this;
         }
         else if(partyInfo != this)
         {
             Destroy(gameObject);
         }
     }
 }

As far as I've been able to tell, it should work.. It's public, it's serializeable... and to top it off, if I attach the Stats script to something in the scene I am able to see it's info, but when I attach the partyInfo it just shows that it should be holding a stats script..

Any ideas? I'm banging my head against the wall here.
