Weird bluetooth pairing for controllable trainer

I have been using bluetooth to connect my devices to my windows PC. (bluetooth dongle)

There seems to be a weird bug that means it doesn’t show the trainer unless i connect it as power first and then it will see it as controllable. I use my powermeter for power and cadence so just means an extra step to pairing.

It isn’t the worst problem ever but just a bit odd that’s all
