I just added quark and zeta earlier today to our modpack, ever since i login or any player joins the server, we get 4 knowledge books.

As you can see my inventory actually has 8 now since I logged in twice. Please help fix :<

This is most likely due to either

a) a data pack using the recipe unlock feature to give items which will break with quark's give every recipe

b) a other mod doing something weird

Quark doesn't touch knowledge books at all and the other user who reported this mentioned it was from another mod.
