I'm having an issue with setting my oath spells' levels I receive them at in the "Additional Specific Spells" section of the basic info; it won't let me set them at all, the spells are not going to the bottom of the box or allowing to click on the spell like a pop up button, like most sources are telling me and I've everything I can think of to fix it but nothing has worked and I don't know what to do. please help.

I figured it out, I had non free spells in the "Additional Specific Spells" box, boy do I feel stupid

Nevermind I'm still an idiot, it actually didn't work 

I'm no longer an idiot, spell adding doesn't work like how I was told from other sites
