HP on Tokens Linked to the 5.5 Character Sheet Refusing to Adjust.

I have been having issues with certain tokens that have the HP attribute linked to the 5.5 D&D character sheet.  When I try to adjust it, nothing happens.  I can't raise it or lower it.  It just stays the exact same on the token.  For some tokens, changing the attribute around, deleting the token and pulling another from the library etc., seems to work, but for others it has not.  There doesn't seem to be any rhyme or reason to it.  Just wondering if others are experiencing this or if this is a wider or known issue or if there is a known fix etc.  Thank you.

I experienced this with one token the other day in my development/test game. I have not had time to investigate it though. 

A friend of mine had this issue a week ago and I'm having it now, can't seem to fix it and have to work around it by manually setting the max health of the bar instead of linking to HP which is really annoying I hope they fix this soon

I suspect that this is related to Demiplane integration, since that seems to screw up everything to do with the token bars in similar ways.
