AFTERPAD

I have a Horipad Ultimate and a steel series Nimbus. I used to be able to run both at the same time and one would pair as player two. This was awesome for local gaming on the Apple TV. Suddenly they both started pairing as the same player - player 1- which means two player games no longer recognize player two. I have done everything (restarted Apple TV, forgot and repaired both, updated software of controller on both, confirmed my tvOS is up-to-date, charged them, and tried all of these in different orders. I hope you can help me. How do I get the Apple TV to recognize the second controller as player two?
