Gem Skill can't be assigned to hotkey

When I logged in today I noticed my Flame Wall Skill is no longer set to a hotkey. When I look at the gem tab I couldn't assign it to any hotkey. Also selecting the empty spot on my hotkey bar doesn't show flame wall as an option. Looking at the more information of the skill shows a weird bugged out screen that says "This information is currently unavailable".

I have tried swapping the skill out and then back in. I tried moving it to a different slot. I tried putting support gems in and out. I tried exiting the game entirely and relogging back in as well. No matter what I do it doesn't seem to work.

I should additionally mention that trying to gem cut a new version of flame wall just eats the uncut gem and gives me nothing.

Edit: Actually the above is incorrect it just stored the new gem in my stash. Also the new gem for flame wall does appear to work. So its just this one specific gem of flame wall that is broken somehow.
