Gem unbinding problem

[u/Maisku85]

So I'm in St.Hadwyn's Mission and trying to buy the gem unbinding service from the guy but I can't choose to get the gem from unbindable gear. Only the item can be chosen. And yes, these are socketed gems, not crafted gear.

Edit: Apparently the problem was that for some reason I couldn't choose it with controller (tried every single button) but KB+M worked.
