Double in playlist

[dhumble]

Hi notice some strange issue with my playlist. Somehow there is double songs and the order isn't same. And the app of Shazams sync playlist has also other songs that i haven't Shazamed.
I have samsung galaxy s8 which is new. Otherwise I haven't done anything different.

How do i fix the error? Get my old playlist back and no double.
How do i contact spotify to solve the problem?

Tanks
