I think it may be because your polar calibration accuracy is wrong.
First, mount the Seestar on the adjustable latitude wedge base and adjust the tilt angle to match the local latitude.
Make sure the power button of the device is facing up and the top of the telescope is facing north.
After starting the device, the Seestar will open the mirror arm, usually pointing to the zenith (that is, directly above the device), and perform the first plate solve to determine the current pointing.
The device will then perform a series of rotations and plate solves to accurately calculate the polar axis deviation and prompt the user to make necessary adjustments until the calibration is completed.
If the polar axis calibration fails, please check the horizontal and compass calibration and confirm that there is no magnetic material interference around. Then click to calibrate the polar axis deviation again.
Please try again.
Or can you send me a video of your full polar axis calibration process?
