Assuming you're talking about levels, check if the "TypeOfLevel" includes "Singleplayer". If not, add that in there.

please describe your issue further instead of... capitalizing everything? Also show your level header as something is going... very wrong for you to be throwing so many random things at it.
I believe you also have to mess with the LevelSelect param in the level header as well to get it to show in the level select, not certain though, you should try what snoc said first if you havent done that already
