My Question or Issue

 When I play my spotify on my phone it plays for a while and then asks or just switches on a playlist from sara. Which I have no idea who it is. When I click on the button to chose on which device to play on. It gives me option for my phone, and Sara. But when I click my phone it goes automatically to the Sara playlist. 

What do I gotta do to change it.
