Launcher doesn't show my versions anymore.

The new lauchner isn't that good, sadly. I'd like to play my profiles with all the different versions of the game, but the lauchner doesn't show the versions which are in my folder, so I can't play them. I uninstalled the lauchner and installed it again... didn't work. I logged out and in again... didn't work.

 

Hopfully someone can help me.
