unable to select custom skin, says limited usage

when I try to select a custom skin, i cannot select confirm, and a message pops up above it that says "limited usage," and when i tap it, it says "only available on specific platforms," despite me being able to use skins made with the same program and the same source before the current update from the play store. (1.11.1.2) I'm thinking it may be because it has "jacket layer" and "pant layer" pixels, as well has "hat layer" pixels.
