for loop not working properly

This is my code:

 List<Word> spawnedWords = new List<Word>();
 
 public void CheckWord()
 {
      inputText = inputText.ToLower().Trim();

      print(spawnedWords.Count);
 
      for (int i =0; i < spawnedWords.Count; i++)
      {
           print(i);

           if (inputText == spawnedWords[i].selectedWord)
           {
                spawnedWords[i].TakeDamage();
           }
       }
       inputText = string.Empty
 }

I link CheckWord() method to the Enter button and when I pressed it, the for loop didn't complete all the loop. Only some of spawnedWords execute OnTakeDamage(). Let say I spawned 5 Word objects, print(spawnedWords.Count) showed 5 but print(i) showed only 0,1,2. Wht is this happening? Please help~
