Symilar to another user's issue, but on Windows. Adding in queue does not add forward, it skips one song, or duplicates or triplicates. Also, moving songs does weird things. Trying to skip to a song by double clicking after this, makes queue say "there's no more songs to be played". It happens in both PCs I've used.
Don't know if it's related, but it also happened that it told me there where no songs, when double clicking a song in an album view.
Thanks for reaching out to us about this - we'll be glad to help you out here.
In case you still experience this, make sure you perform a clean reinstall of the desktop app on your device. This will ensure any corrupted data that might be causing the issue get removed.
If you see no change after the clean reinstall, send us a short video showing what exactly happens on your end. Just attach the video to your next response to us by using the Insert Video option in the post editor.
