Can you create playlists on shares?

Hi
Relating to playlist creation and management from within INFUSE.
Not sure if i’m missing something here
Got a Plex, JellyFix and Emby share set up.
I can select a movie and go to Playlists - Add to playlist (or create) and it looks as though it does it but then when I go to playlists the playlist I have created is there but there is nothing within in.
I’m using direct mode.
I can also only see the playlist I’ve created on a per share basis (I can’t see the playlist I created adding a plex movie when trying to add jellyfin)

All playlists created outside of infuse via the respective apps show up and work as expected.
