Playing a Daily Mix add all songs behind the queue (and not clearing the queue)

[Aristos]

When a play a Daily Mix, the playlist from that Mix is added at the bottom of my queue. Leaving all the classical music from my wife in the queue. It starts playing the first song from the Mix, but the next song is from my wives classical music (we share Spotify).

Of course I can delete all old (classical music) songs by hand, but this will take a lot of effort, and I encountered this problem for the third time now. Same problem at my wifes iOS. 

Also I am not able to delete the queue with selecting the blue dot of the last song at the queue. This will only delete the last song.

Any help?

Somebody? Spotify is getting useless for me, when I have to erase a whole playlist everytime a want to listen to music.
