Why is my old projects not showing up in the Unreal Launcher?

Hej,

I have recently updated Unreal to 4.8. After the update, My projects which i created in 4.7 are not showing up in Unreal Launcher under “My Projects” section. How could I set my old projects to display on Unreal Launcher?

P.S: I can able to launch my projects by double clicking the .uproject in my project folder.

Thanks for your time!!!

The problem is already known!

Or is it something else?
