(Settings) Playlist filename template not applying variables

The "Playlist filename template" under the Downloads settings doesn't apply the variable.

I've tried "playlist", "%playlist%", & "%playlist_id%". It creates the file as "%playlist_id%.m3u8"

It works as expected for the "Cover name template" setting. Variables are used properly.

Extra Suggestion A setting to only create a playlist file for playlists and charts At the moment, it also does it for albums.
