Can't use custom models for mobs

Issue description

So I apparently can't use custom models for mobs, which I really want to do. When I click on the list of available models, my custom one, which I've already imported, is nowhere to be found. Neither is the texture that I created to go with the model. It does work with blocks, though.

Issue comments

The issue is that you have exported the model as JSON. MCreator mobs only support JAVA models, so export your model as Java.

I had the same issue, and I'm starting to think I should try other software for this because this one clearly is unable to do one of the biggest parts of making an addon.
