Problem encountered on version "createdieselgenerators-1.20.1-1.2h.jar" not the previous one

When using the mod, all Create mod items gradually disappear from the creative menu and from JEI.

Each time I restart the game or the world, a few more items disappear from Create until the tab is completely empty.

Same on 1.20.1-1.2i (But that can also be because of the other 79 mods I have installed, but items aren't disappearing when I disable the create diesel generators mod)
