Unable to List Skill Gem in Store

I am unable to list the skill gem Searing Bond of Detonation in my vendor shop. It its greyed out the way that portal scrolls etc are. However I can see that other players are able to list the gem in their stores. Any idea how I can fix this?

Can you still newly list other items? Sometimes the store gets frozen and prevents loading things to sell. Resetting the hideout instance can fix it.

If it is just those specific items, unsure. Is it letting you list other gems? I think that is a new gem transfigured gems? maybe it is not compatible with asynchronous trade yet. The wiki doesn't seem to have a page for it yet.

I can list everything except for gems.

Hmm. That's strange, I can list gems on standard currently. Can't test on mirage as not in trade league.
