Translucent block transparency issue

To keep it short, this is the model in blockbench:

But in game, in almost every angle, it looks like this:

It keeps appearing and reappearing parts when the angle it is viewed changes.

I already tried messing with the configs, texture, model, pivots, bounding boxes, everything, and don't seem to understand what really is going on. Doesn't Mcreator support models inside translucent textures? I would greatly appreciate support on this.
