Bug - Traffic light key function not working on soundcloud music?

Anyone knows if this is a bug or a feature: i got my key indicators flashing traffic lights working with the collection that is on my pc (using a DDJ FLX4 and pc) but when i get music from my soundcloud playlist the "master" button above the playlist is gone and eventhough the keys are still displayed, it does not mark in green the matching ones. Anyone else have this too?
