Hey there. When I enable this addon and do a dungeon, the Grievous affix does not appear on the raid frames. I tried to adjust how many debuffs on the frame in the settings but it still didn't show up.

I have no addons for frames, I am just using default raid frames.

This has happened to me as well. Default frames nothing I changed allowed grievous to appear. Disabling the addon was the only way i could see the debuff
