Garmin Cadence 2 Sensor Low Reading

Hi,

New to Zwift and looking for some help.

I have a standard Elite Volare Mag turbo trainer with a Garmin Cadence 2 Sensor. On my first ride today, the cadence was floating around 66, which from road riding experience I knew was way too low. I turned my Garmin device on to see the cadence where I would expect around the 95 rpm mark.
Any ideas how to get this to read properly on Zwift please?

Note: I used the app on ipad Air 2. Plus companion app on Huaweii P20 Pro, both showed the same data. The Garmin Edge 1000 showed what I would expect.

Thanks JD
