Can't see my character sheet

I cannot see my character sheet; there's just a big white space.  Other players can see it.  The DM confirmed that he assigned me to edit and control my character sheet.  I can successfully edit the avatar and the name.  I can see and move my character token.  Is it possible that something on the Attributes and Abilities tab is preventing me from seeing the character sheet?

This happened to me the other night at the end of a long session(4-5hr).  I was able to just reload/refresh the game and it worked again...  Using chrome btw.
