Apple Music Windows - Setting Favourite for one song sets the entire album
Sometimes, when I click the "favourite" spot on the line of a given song, simultaneously the favourites markers are set for the entire album. Clicking again turns them all off again. As I cannot see anything wrong or ambiguous in my actions, I'd say this is a bug not a feature. Sadly, Apple Music on Windows still seems to be riddled with bugs.
