Frontend custom launch profiles not cooked maps

I’m developing a mobile game using Unreal 4.8.

I want to select a map in Custom Launch Profile, but no maps are displayed.
I just can see the message [Cooked Maps: No Available mpas were found.]
What can I do for this?

I’m having the exact same issue in 4.7.6

Put your maps (.umap files) inside the Content/Maps folder.
