Entities with Custom Models are Invisible

In the latest version of MCreator, any Living Entities with custom models, (or Animated Entities with the GeckoLib plugin), are not rendered, and neither are their hitboxes or their outlines with the Glowing effect.

The way I know that they even spawn is because in the testing world of all of my mods where this happens, I have a repeating command block that summons a big particle at the custom entity's position, so I know where it is.

For the Living Entity element, if you instead choose a default model like Biped, it will show, so I don't understand what is going on.

I tried changing the textures and models and even remaking the entire entity, but nothing works.

This has been a consistent issue in all of my mods, so I would like if this bug was looked into and fixed as soon as possible.

Any help would be greatly appreciated!
