When this addon is enabled, the ElvUi skin is forced on the Transmog and Appearances tab, checked Elvui Skins tab, AddonSkins as well, the issue seems to be on BetterWardrobe.

I have the same issue. New to this addon since Mogit is broken. Would love this to be fixed.

This is happening for me, too. Both the appearances tab and the Transmogrify screen (at a Transmogrifier or on the yak mount) are using ElvUI's skin, even though I have Blizzard skins enabled.

In addition to this, the labels on the tab buttons along the top ("Sets", "Extra", and "Saved") are even further misaligned than in OP's screenshot. They overlap the top of the main section.

Should be fixed in the next update
