When ever I open the Villager editor, the menu form past versions isn't there, Instead bars where you type the name of a profession, and the skin are in it's place. It's really frustrating, for changing what they look like, or their profession.

Steps to Reproduce
Once your in your world, get the editor and right click the villager, and you'll see.

Minecraft Information (please complete all questions entirely):

• Minecraft Version: 1.12.2
• Forge Version: 14.23.5.2838
• MCA Version: 6.1.0
• Launcher: Standered

That's because MCA 6.0.0 was a rewrite of the mod, which means it is being essentially remade from the ground up. Many of the features from 5.x just aren't there, and the experience feels... weird. I started using MCA years ago and even then it had some features that the newer versions lack.

One option would be to revert to the latest 5.x version for 1.12.2 but you'll lose all your progress. But if you want all the features from that version, your best bet would be to downgrade, this projects seems abandoned, which is really sad.
