Bug when refilling weapons?

[Choom]

Okay, so when I try to refill the charge on my enchanted weapon, it brings up a list of the gems I could use. However, it only shows the top 3 gems, and I cant scroll down to use any of my other 100 gems or so. Is this a bug or am I doing something wrong?

You should be able to scroll down. I do it all of the time. Do not know why this would glitch unless you have a lot of filled gems of the same sort, in which case they will all be clumped in together and not shown separately.

Originally it worked, but all of a sudden it just started doing this
