To Reproduce

Screenshots

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?
No, because it worked before one of the last few updates, i only noticed it due to the warning of a lot of addon issues so installed bug-grabber because of it

Which version of DeadlyBossMods are you using?
DBM-Core-11.0.3

Was it working in a previous version? If yes, which was the last good one?
Yes, but i'm not sure which
