Unable to transmog a Collected Appearance bug

I’ve collected the appearance for 4 one-handed swords, yet they aren’t showing in my actual transmog screen. They are the Freezing, Unholy, Burning and Crimson Sabre of the Ebon Blade. I have verified that they are in my collected appearances log. I’ve also gone and purchased the weapons once more, but it still isn’t giving me the option to transmogrify them. I then made another Death Knight to see if I was able to transmog them on that character, but no. I wasn’t. Could anyone offer assistance? Thank you.

Still having this issue.

Bumping to stay relevant so this constant issue I’ve been experiencing can be resolved.
