Spotify 'now playing' bad bug

[jezza1685]

I have noticed quite a bad bug on Spotify on my iPhone today, when I'm playing from a playlist and I scroll down in the playlist to find the song I'm playing at the moment, the highlighted green song isn't actually the song that's being played. I've seen it with all the songs so far while playing in this playlist, has almost 100 songs.
I'm using the latest Spotify (4.0.0.919) on iOS 9.0.2

Just now, I noticed with a song I'm playing from the playlist on shuffle play, there isn't even a highlighted song when the song is meant to be highlighted when it's playing (obviously). All of this happens in the 'edit' mode too for the playlists to be clear.
