UNKNOWN_PHASE_ESTIMATE/ Encoder Error/

hi,
I am working with two set of ODriver V3.6 + 2 encoder CUI AMT102-V + DUAL SHAFT MOTOR - D5312S. I am having error with only one set.

I don’t get errors when i did the calibration but i get MotorError.UNKNOWN_PHASE_ESTIMATE when i run dump_error.

and odrv0.axis1.encoder.config.pre_calibrated doesn’t change to True, it also ways returns False

The voltage/ value of the PIN ‘B’ on the odrive i having errors with doesn’t change, they just read 0.09V. Is this an error? Because on the set that works, value fluctuates. Is this because of the encoder or an issue with Odrive, or is this not a problem?
