I use two magic weapons and they require recharging fairly often. I notice that I get only three choices of soul gems to use even if I have a dozen or more in my inventory. If I want to use up my commons or lessers before my grands, is there an easy way to do that? Right now, the only way I see is to trade the grands to my follower to get them out of my inventory. I want to save a few grands for enchants, etc.

It's a scrollable list......

You need to scroll down more.

I don't know what's happening, but I just go to the gem and click X for charge.

Hey. I don't know if it's been mentioned, but you need to scroll down some.
