Level select bringing up levels that don't exist.

Hello. I've been recently trying to get used to the in-game map editor. I wanted to keep all the default maps,i.e. not have large untextured roads running through them.
I never modded a game in my life. I made a copy of the grid-map in the level folders, changed the file names (In the info.json file). So I started making roads along the map, getting used to using the rotation and positioning aspects of that tool. About 30 mins later I decided to take a stab at making a good map.
So I deleted the grip-map folder I made. I went to the level select to play a level and I noticed there is still and option for it labelled "First Level". I looked in my map folder and it isn't there. When you click on it, it brings up a box (Look at attached pictures). I have bought the game on steam, so it is not pirated. I re-installed the game to try remove it and nothing happened.
