I can take spells which I already have

[wih]

Aloth has Form of the Helpless Beast and Chain Lighting in his spellbook. Nevertheles, on the level up screen these spells are available for taking. I can actually take them again. After the level up I still have those spells. But I have missed out on taking new spells. Aloth now has less spells than he is supposed to have.

 

Same with Call to Slumber.

The other spells I have are marked with "Already have" on the level up screen but these three aren't.

 

P.S. Also Rolling Flame.

This occurs because the spells in your grimoire are not "known" by Aloth, he is able to cast spells in a grimoire but if you change grimoires then he can no longer cast those spells. 

 

The spells you learn each level are spells you will always have available regardless if you have those spells in your grimoire or not.

Yep, not a bug

Oh. I didn't know about this distinction. The game is ok then.
