How do you perminantly get rid of a gekolib animations folder in mcreator 2021.3

Every time I make an update to my mod there is a lingering animations folder that has a mob in there that i didnt want anymore, and it keeps popping up no matter how many times i delete it, if i delete it every single time its fine, but i dont want to have to delete it every time, it is very annoying, not only that but it doesnt show anything in mcreator itself, i titled the model "grim" and its been literally haunting me ever since i deleted it, i deleted its texture, its model, its name, its procedures, everything from mcreator, but the file STILL lingers when i update the mod, please help
