Problems with adding songs to playlists in audiotube

Whenever I try to add a new song to an audiotube playlist, the menu it shows is empty, even if I have playlists. Running audiotube via the commandline I can see all the sql queries it makes, but it doesn’t make one to get my playlists.

Hi,

on which version of AudioTube does this happen?
It seems to work in the nightly flatpak for me.
