As the title says.   When I drag a token from either the Compendium or from the Monster folder the tokens are missing the default token therefore does not show up.  I have to edit the token, delete the default token, set the HP/AC, and then save the default token to get things working.   This only started happening tonight on a new curse of strahd game I created.  As you can see in the image the default token which saves the character information is blank.   Every monster in my compendium for this campaign is this way so far.
