Return of Reckoning

When I target a mob that has a red name there is a big red square on it and it covers the whole mob but becomes smaller when i get closer. Is orange on an orange mob blue on blue person like a guard. I have turned everything off but Yak Ui. However there are some addons that appear to stay on no matter if I turn them off. I deleted my user and interface folders and replaced with yak ui and have put no other addons in there. The square is annoying and I would like to turn it off. Please help me and is there a way to turn on mob hp in warhammer interface or a addon that will do it. thxs

Shameless bump

If its only on targeted mobs it might be an issue with Effigy addon that is missing some shared textures.

More pricecley i think it is the Target-ring section in Effigy that should draw brackets ( ) around the target that is missing the required textures

which way did you install your UI?
