Why can't I teach my follower spells through tomes, even though I am using Ultimate Follower Overhaul?

It claims that I can teach a follower a spell from a tome, but I am getting nothing.

What is my problem?

From reading the posts on the mod page, it sounds like the UFO port didn't go too well and a lot of people are having issues, so you may want to consider switching follower overhauls for your next playthrough. That being said, can you read the spell tome yourself and teach your follower the spell that way?

Nether's Follower Framework will do that - can toggle in its MCM. I use it in my current playthrough.
