I can no longer roll dice from my character sheet

So, I've been playing in this (D&D 5e) game for several months. A few weeks ago everything was fine, but now I get error messages every time I click some trait on my character sheet that triggers a roll. For reference, the game is called "The long night" and my character's name is "Keeper." My DM can still roll dice from my sheet as always, but (for example) if I make a Strength saving throw, I get "No attribute was found for @{Keeper|strength_save_roll}" I don't have any other obvious problems with my character; I just leveled up earlier and everything updates normally. The numbers all look fine, I just can't roll dice. (I still seem to be able to e.g. post something like a spell or ability description from my sheet, just nothing that triggers a dice roll.) I get this problem regardless of which web browser I use (tried both Edge and Firefox). Does anyone know what the issue might be?

Try changing the name of the character to something else, and then back to Keeper. It should not have trouble finding your attributes.

So, if I change the name to something else it works fine. But if I change it back to Keeper I have the same problem again. I mean, I guess I can just leave the name as "Keeper 2.0" in the meantime, but I'm very confused as to what the problem is. As previously noted, my DM has no trouble rolling for me regardless of name. Thanks for the help.

I am having an issue with something similar. D/D Beyond+Beyond 20 not rolling into my custom game. But works fine in another game. Logged in as another character in my custom game and able to roll fine.  GM of custom game not able to roll using D/D Beyond+Beyond 20- 

It sounds like there might be some weird duplicate sheet thing going on - ask your GM to check if there's another copy of Keeper in the Journal somewhere. If you don't have permissions to the duplicate, your Attribute calls will fail but the GM's will work. That's my best guess, anyway.
