Kurt kinetic smart control pairing with Fenix 5x Ant+

I have a Kurt Kinetic t6400 smart control trainer that does dual broadcast in Bluetooth and Ant+.

however I cannot get the Fenix 5x to discover it. 
I can pair the trainer to my laptop and iPad as power and a controllable via Bluetooth

and I can pair it to my laptop as power and a controllable via Ant+

I’ve contacted Kurt kinetic support and they’ve told me that the trainer broadcasts in the standard Ant+ protocol and there shouldn’t be any issues on their end.

I cannot get my Fenix 5x to discover the trainer power meter at all

i’ve also tried my wife’s Fenix 6 and her watch also fails to discover the sensors from the trainer. 

any help would be appreciated.
