Project not opening in correct editor version

I seem to have a configuration issue somewhere. I have a project on 4.22 and it opens on 4.20 if you click the project icon in the project folder but if you go thru the launcher it will open it correctly in 4.22. Of course I get a message saying the map was made in a newer version and cannot open it.
I reinstalled UE4 recently but it still has the issue, only on 4.22 projects. New projects produce the same effect.
Does anyone know how to correct this?
