The response below assumes you are using the CelestronGPS driver for the AVX.

This driver 'protects' the hand controller mount model by not allowing setting either time or location after you have gone through a HC initial aligment. If you set the location or time after the initial align, the HC internal model will break.
-BUT- if you never use the HC for anything and only use computer commands, even if you set the location or time and then do a force sync, everything works fine from the computer.

I had a discusion on GIT about this, see
Time/Date/Location in Celestron GPS driver.
if interested.

I modify the driver for personal use by removing the 'check_aligned' check and allowing it to pass through as only the computer side is used and never the hand controller.

Now how to get 90 degrees out, does your location match in both kstars/ekos and the mounts site settings?
Even if the date and time are wrong, solving near the NCP should give you something near the NCP.
What RA/DEC does it show for the solution?
