Just obtained Aloth in my party and not long after I was able to level him up, I noticed he came with a grimoire which shows 2 spells for each power levels 1 to 9. When I go to level up, the ability upgrade screen shows the spells he knows without the grimoire equipped as "known already" but not the 2 skills he knows in the grimoire. When the grimoire is equipped it allows me to upgrade to those skills even though he knows them already.
If I choose a skill in the grimoire to select, it slightly upgrades it's damage and shows the skill twice under the character statistics screen. Is this normal or a bug? I was quite confused when it came to leveling him up.
