Is there an issue with changing FURL in custom apps? Here is an example of what I'm trying to do

to

But it keeps on adding the top level furl app name for me after saving

My furl.json file for reference.

{
	"topLevel": "collections",
	"pages": {
	    "collections_add": {
	        "friendly": "add",
	        "real": "app=collections&module=collections&controller=submit"
	    },
	    "collections": {
	        "friendly": "",
	        "real": "app=collections&module=collections&controller=index"
	    }
	  }
}
