object field decides when it wants to work,Why does my list clear itself

I have 3 lists

 private List<string> variables = new List<string>();
 private List<int> choices = new List<int>();
 private List<object> contents = new List<object>();

i populate them

 public void addCount()
     {
         count++;
         variables.Add("New Item" + variables.Count.ToString());
         choices.Add(0);
         contents.Add(new myObject(0, 0));
     }

my object

 public class myObject : object
 {
     public int aValue;
     public int anotherValue
 
     public myObject(int aValueIn, int anotherValueIn)
     {
         aValue= aValueIn;
         anotherValue= anotherValueIn;
     }
 }

if i call addCount 3 times and call Count variables.Count = 3; choices.Count = 3; contents = 0;

no matter how many times i call addCount contents always returns 0 when i run the game.
