Please fix the creative tabs for ease. Your tabs should be placed in one setting.

Do you mean the creative tabs are placed separately instead of together? It seems not what I can control. In the code, I wrote them together. I'm not sure how the creative tabs are sorted.

This happens in 1.20.1 too, however other mods have the same problem. For example, Create and Create Steam 'n' Rails.

It's probably just another Minecraft bug.
