When playing on my PC, random tracks from my history/playlists are showing as "playing" on mobile

 Has anyone noticed this? It is incredibly confusing. I will be playing as I often do on my PC, and when turning to check my phone it's telling me a completely different track from somewhere in my history or playlist is playing. The time slider is running and everything, it really looks like that track is playing and I can pause and restart it from mobile too.
