Bug Asset Bundle clearing List elements

Currently I have these three list's that contain these elements

Code (CSharp):

1. public List<GameObject> mediaPanels = new List<GameObject>();
2.     public List<Button> continueButtons = new List<Button>();
3.     public List<Button> backButtons = new List<Button>();

There is nothing within this script that clears the in Start or Awake methods.

Once I build an Asset Bundle and load into it, the List's clear for some reason with size of 0. When I play the scene through the editor, the list does not clear, so I believe that it has something to do with the Asset Bundle build. Not sure what is going on. I also have other List's within my Asset Bundle that do not get cleared but these do.
