Can't remove playlist name

I have a Fenix 5+ and I have uploaded music files via Garmin Connect and via Winamp through Transfer to device.

Now I have deleted the playlists and songs on my watch (either Connect or deleted via explorer) to upload another playlist and mp3 files via Garmin Connect

It shows no music (Music folder empty, Playlists folder : empty) which it's normal.

I have uploaded the new playlist and files (Garmin Connect), it's ok, but I see some previous deleted playlists with no music.

How can I remove the deleted playlists from the watch (with no songs associated) ? besides hard reset ?

I rebooted the watch, same result, they appear even there's no music file (song name) associated.

When I browse the watch via explorer or Connect it shows no playlist name which I want to remove.

From now on I will use only Garmin Connect to upload playlists and songs.

Thank You,
