Leatherworking Specializations Not Functioning

When I open the Specializations tab in my Leatherworking, there’s no trees to view, no wheel to add knowledge to, just an Unlock button sitting in empty space, a janky wheel to the right asking to learn sub-specialization, and an Apply Changes at the bottom.

I’ve gotten this on multiple machines, with and without addons.

I’m also getting this, but for Enchanting. I have Tailoring and Enchanting. The tailoring specialization page works just fine, but Enchanting is broken. I’ve looked on another character who has Herbalism and Alchemy and both of their specialization panes work as intended, so it’s not a consistent problem across all characters on my install.

A workaround is (or might be) to unlearn the profession, then pick it back up again. It’s a huge pain to get those levels back considering how expensive everything is, but I was able to at least open the enchanting specializations pane.

This has been my main since vanilla and I’ve been a LW since vanilla, not planning to re-level every single type of leatherworking and rebuy dropped recipes

As of today it displays my Skinning specialization in LW.
Still can’t see my LW specializations

Still nothing

I am also facing this issue since launch. I cannot do anything with my skinning specializations. It’s either a bugged / broken / unusable UI OR it shows my LW specializations.

I have professions on other characters with no issues. Does anyone know if I will lose my knowledge points if I drop my skinning and relearn? I probably have a tonne unspent I cannot access…

10.5, still broken

Keep being told by GMs they don’t have an ETC for a fix, still can’t engage in expansion feature content
