Bluetooth cadence doesn't work! – BioLogic BikeBrain – GPS bike and cycle computer Review

Doesn't work with Wahoo RPM Cadence Sensor. Pairs up with sensor OK but slowly alternates 0 and 180 on screen when cadence is actually 80 - 90. I have 50 rides logged this year on Bikebrain so I'm disappointed to have to switch to Wahoo Fitness App which does display accurate cadence as well as speed, time, miles, etc.
