Deleting an Interior Room

Hey All!
Just finishing our Toy Box Summit contest entry and we suddenly had a weird thing come up. For some reason, an interior got attached to our toy box. We're not using it, not sure how it got there. But now, anytime anyone spawns into the game, the spawn into that empty room, and not our level. Then, you have to go through the door to spawn into the level. When we try to delete it, it says the interior room is at level one (and there is no option to delete) while our actual toy box is at level 2 (and we can delete that one.. but we obviously don't want to). So how do we get rid of this random interior room. It's just an empty room.. not used for anything. Or are we going to be stuck with it and have to find a way to add it to our story. And if we are stuck with it, will it make it impossible for Disney to hook up our leaderboard? (I read somewhere that toy boxes that need leaderboards hooked up can't have added on rooms.. not sure if that's true.) Any help or advice? Need to submit tomorrow night!
