Connecting with Ant+ & Bluetooth simultaneously

I’ve noticed that when I connect up my Stac Halcyon to TR on my Android it connects with both Ant+ & BLE at the same time. Should I unpair one of them or just leave it as it is?

Resuming this old thread.
I have the same problem. I wish that it only connected through ant+. Do i have to set bluetooth off for this to work? During my last ride with both bluetooth and ant+ did my power disappear. To connect with only ant+ i had to close the app, set bluetooth off, start the app and resume workout with only ant+.
