Torque Value is jumping after calibration

I have a brand new pair of dual-sided Vector 3 Pedals. I am using them with my Fenix 6x Pro.

I used to have a Powertap C1 Powermeter and after each Calibration I got a static Torque value displayed after calibration; most of the times it was shown to have 0.00 Torque offset.

However, after each calibration of my Vector 3 I get a Torque-value after successful calibration, which is never static, but that value is constantly changing. Most times the showing values are between +/-0.2. Is that normal? Why are the values constantly changing even though the calibration was performed and nothing is being moved on the bike. Are my pedals flawed?

Thank you for your help.
