I am not sure if it has been reported in the bug section before or not. The right click on abilities not in a spell book is a new feature and new descriptions need to be made for all the abilities that either had an invalid description or lacked a description entirely. Most of the abilities not found in a spell book actually fell into those categories (the Bioware devs saw no need to make descriptions, since no one would see them anyway) so giving them new descriptions is a work in progress.
I made a report of it in the BGEE section, no response from anyone though, so I have no idea if they know about the ones I found so far. I know it's from BGEE but some of these may still be relevant for BG2EE.
