Also posted this in the comment section of the addon itself. However, I hope I am not the only one with this problem.
I have a problem with my targetdebuffs. In the Debuff section of the bargroup it says that only buffs from the player (me) on the target would be visible, however, it shows ALL debuffs from all the players on the target.
Anybody has the same problem? And is there a solution to this? Thank you in advance!
