So I was making a new marking. I do have Legendary markings installed but I don't think that should be an issue.
Anyways, the Canine body and head markings don't show up as the marking I made. They show up as the first markings on the list. But for some reason, the tail markings IS working.
Under [cHead] and [fHead](Bottom of the list, under the other markings) I have
Marshmallow;cmarkMarshmallowHead.png
Under [cBody] and [fBody]
Marshmallow;cmarkMarshmallowBody.png
Under [cTail] and [cHead]
Marshmallow;cmarkMarshmallowTail.png
And I just don't get why the tail works but the others don't. Also, the tail ONLY works for the Canine. (I also tried renaming the Tail to fmarkMarshmallowTail.png but then it still didn't work for the lion.)
