Possible problem with Sense's sol playlist

[Gezzer]

I am not sure that I am using right in Sol playlist.
After new playlist Sol was created from Favorites. I go to Sense, open the menu- pressing Playlist button:
A list of playlist sol would show up, press twice on the wanted playlist, sees a white little point which mean loading, but nothing showup after that, the current song wasn't changed at all.

I guess that I don't using Sol Files right or else I have Issues in the system.
Solution suggest are welcome

Thank for reading.

The playlist function fills the favorites list with the songs from your playlist. Since you made a playlist from your favorites, you didn't see a difference because the tracks were already in your favorites.

Ok Now I cleared my favorites list and tried again.
Unfortunately, the Favorites list is still empty after I tried to select some playlist sol

I guess nobody have any idea what is the problem?
It seems to stay the same, I have no access to the playlists sol which I saved in Manger Playlist- I can't play or listen to them
