Friends' Activity has Disappeared from Spotify [MacBook Pro]

[themuppetry]

I still have the sidebar with all my friends' activity on the side of the application. However, when I used to go on artists' pages, my Facebook friends' profile picture icons would appear under the number of monthly listeners on the right. This doesn't happen any more (find attached screenshot).

I still have my Facebook connected to my Spotify and still follow my friends on Spotify. 

Please can someone tell me how I can get the profile icons back on the artist's pages, so I can see which of my friends listen to which artists.

Thanks!
