Transmog not allowing for change

I don’t see any error, but when I try to change my transmog, I hear the sound that normally happens, but nothing changes I’ve tried closing the game down, and relogging, but it doesn’t help. I’ve tried a different on the same server, same account, and transmog works normally. Any thoughts?

Update: I found the trouble. Turns out the 1H mace I wanted to use to mog over my heirlooms is the Corrupted Mace, which is apparently still flagged as a Main Hand weapon, so I couldn’t use it on my offhand mace. That interfered with the entire set. Picking a different weapon to use allowed the transmog to work.
