Messup with Casters

I've been using the dummy model for my spells involving projectiles(I didn't use the actual projectile functions) but I found now that when these dummies are near shops they get that stupid arrow above them....how can I fix that?

Edit: I tried removing the art and stuff from the shop abilities but it didn't work.

Have you tried with the 'Aloc' ability?

use Aloc, I have many shoops in my map and never got that problem so Aloc protects them
