Level up Bug for my whole campaign

Hey Guys!  Ive looked at so many threads but nothing fixed my problem. And btw sorry for my english :D Yesterday my group Finished their first adventure. I uploaded the characters in to the character vault and tranferede them into the new adventure "dungeon of the mad mage". They got their Level up and every single one of them were stuck at the roll HP Window. They could close the charactermancer but not roll for HP or do anything else. I dont know were the problem is and could not find any solution in the community hub I hope you can help me^^ Have a nice day 

There was a similar problem reported in this thread . It seems like there might be a bug in importing/exporting characters and using Charactermancer. Just to check - if you create a new character in the campaign, does it level up OK? The previous thread was locked, and the OP was asked to make a Help Center request - that might be the best way forward. The Charactermancer data that transfers with a character sheet looks pretty messy... I'm not even going to try to unravel it.

Did you set Compendium Sharing to yes? I had the same problem and switching Compendium Sharing was the solution.
