I'm using "anchor to UIParent" setting on party and player DR's and whenever my DR timer shows on player, it duplicates it to party1. Party1 will still track DR's actually cast on party1 and those won't duplicate to player, but anything on player will also go to party1 (and refresh as if it was applied to party1 directly). It also happens even when party1 doesn't exist.

I'm assuming this has to do with the fact that when not using "anchor to UIParent", that player is in the default raid frames. So that might be the source of the bug (unless I'm really missing something here).

Should be fixed now in v2.5.7 I think, if not just reopen ticket.

(If it still doesn't work can u double check if toggling "Use Compact Raid Style Frames" option in Blizzard's edit mode changes anything?)
