Custom model wont compile after renaming

I have two different elements in my workspace with two different custom Blockbench models. When I try to upload them to the Resources tab, I have to rename them both because they will have the same name (Modelcustom_model) and MCreator doesn't let you proceed without changing one of the names. After I do that in the workspace folder, it says there's an error while compiling the element. I know the renaming is the cause because if I don't rename it and leave the name as Modelcustom_model, it compiles normally. 

Is there any way to get around this? Something I'm not aware of? I've only just learned how to use MCreator so that could be the case.
