When I add this feat it marks it as not complete unless I pick 6 spells and none are showing up in my spellbook. I am getting the +1 bonus to my stat just the spells seems to be off. I have tried both on my iPad Mini and my Macbook Air. I use Google Chrome on my Macbook. When I first noticed this I was adding it as an extra feat we earned and not from hitting one of the lvls you get a feat. I did try to go back and add it through my lvl 4 feat choice but no difference no matter how I try to use it.

Can you share the character? I assume you are a wizard and are looking in your wizard spellbook. That is not (I believe) how the feat works, and the spells will be displayed seperately.
