Pickup mode not working with Traktor Kontrol S3?

I’m in the process of midi mapping my new Traktor Kontrol S3 and I discovered that pickup mode isn’t working properly. When I try enabling it on various knobs they all behave as though pickup mode is still turned off. It’s strange, though, because it’s working fine with the tempo slider.

I poked around the forums and did some googling and found another post documenting the same issue but there didn’t appear to be a solution. Let me know if I’m missing something. I made sure my firmware and app are up to date and tried turning everything off and on again but no luck.
