I'm playing on 1.7.10, where the enchantment table doesn't use lapis. The pack still shows a lapis slot when it shouldn't be there.

This one totally flew under my radar when transitioning to the revamped graphics. Noted!

Fixed as of Beta2

It's fixed but I originally downloaded the wrong one as 1.7.10 and 1.8.9 are labelled the exact same on Modrinth (and the 1.8.9 one is shown when filtering for 1.7.10).
