Issue description
I don't know if anyone else has had an issue but, when I import my custom-ly made models(in Blockbench) they do not get added to the resource tab. I don't know if this is a blockbench or mcreator bug as when I imported a silverfish model, it got added.
You most likely have one model with the same name already imported. In the Java code, your model is called unknown. If you add another model with the same name, it will only overwrite the current one.
