Edit playlist heavy glitch

[Quietwar]

I just installed the new update as of yesterday. When I drag & drop songs in my playlist to change the order, the songs ive selected ti drag - duplicate. When I ht done, I realize spotify moved other songs (at random) instead of the ones i selected when I hit done. When I delete duplicate songs, spotify will actually delete other random songs I have not selected.

I'm a premium user, and would like this resolved soon.
