The Normal Setting would be that the " Out of Combat " nametag of a Mob is Red, Which is the case.
Once upon entering Combat with said Mob the outer Area of the Mobs nameplate changes into " the spikes " which indicates that i have aggro on this mob.
The ISSUE that i am having right now is once up on combat entry " EVERY MOB " that I AM NOT " in " Combat" with in my area of view gets the " Spikes " around their nameplate and the one which is IN COMBAT is just blue... ill drop a picture below for reference.
The Problem disapears once i swap SPECS to Windwalker ( DPS ) there it works perfectly fine but as soon as i swap back to Tank ( Brew ) said problem appears again.
Ingame Settings are like that
Theme : Neon
First Spec Damage ( It makes no difference if i swap it to tank. playing Brewmaster )
Secon Spec Damage
I changend nothing inside of the Interface settings of Tidy Plates ingame.

To Clarifiy the Pictures again. I am in COMBAT with the BLUE Tagged MOB right in Front of me, NOT THE RED ones in the back.
