Playlist Items playable, but whole playlist not

I am really confused, I have a DLNA-Server for Music on my network and it works pretty well with the homeassistant media panel, thanks for that ha developers, but I also store a few playlists on the same server. So if I click on the playlist and choose one song it plays flawless, but if I click on the blue button to play the whole list, it says “Object has no playable resources”, which I don’t understand because I can play every single song.

Thanks for help,
Luis
