Cadence out of control

Anytime I get to 96rpm or above, which is my typical cadence (95-100rpm), no matter the power output, the app immediately shows me 120+ rpm. This will only change if I drop my cadence to below 90rpm.

Wahoo Kickr Core is the trainer.
My wife beside me has the same trainer, and her cadence is typically under 90rpm, no issues.

Thoughts?

Hello,
Sorry for late response.
We couldn’t reproduce your issue on our devices. Are you able you check this cadence on other other device (Your wifes trainer)?

Br,
Marek
