Player skulls

[freak-dk]

Ey

I am trying to check if a placer has a specific player skull, spawned with the essentials /skull command.
%checkitem_mat:skull_item,namecontains:SkullName%
No matter what I do, if I check on just a fraction of the name, use/don't use colour codes, use Nameequals, no luck, I can't get it working with normal player heads.

I can get this working with a HeadDatabase head without issue but I just cannot figure out how to use it with normal skulls?

Might be a bug, but may just be me doing it wrong :p
Would appreciate any help on this!

Thanks
