Prepared spells and abilities should show up in pup-up bars corresponding to "powers" "cantrips" "1-st level spells" "2-nd evel spells" "3-rd level spells" etc. I find myself clicking on the little 1-st level spell flap expecting in to extend upwards and showing me my prepared 1 level spells.
I have as well now that I switched my res, sadly this problem is avoidable if you look on the spell your clicking. 2nd level ones have II on them, to show their second level, or can just hover over it to see it pop up and read the level for the spell. Though if your like me, yeaaaah I forget at times, gotta kill em all fast as possible. lol
