That is the expected response (because it is correct.) That is why you need to delete the part with delete minus then close Fritzing, because the delete only really happens when Fritzing shuts down. I didn’t think, you also would need to delete the part from your mine parts bin before doing the shutdown as it is likely in there too and if it exists anywhere, the new copy won’t load because both parts are using the same moduleId (I was too lazy to change it.)
