Lorebook unattachable?

So I just spent… several hours, building a lorebook, got to 141 entries, most with between 300-500 characters.

I finally decide it’s done for now, go to attach it to my bot, and it tells me I can’t because the lorebook has rejected entries… what?

I had some entries I had to fix as I made them, like ‘minor wounds’ I had to change to ‘small cuts and scrapes’, but I did that to every one with errors.

There’s no flags or anything on the lorebook… I’m not sure what I need to do/change to get it to work?
