You can clear PAE using UTILITY Function > PAE > Clear PAE data
Its worth doing if only to eliminate as a possible cause.

This doesn't sound right. Pressing the ESC key for 2 seconds initiates PAE which is Positioning Accuracy Enhancement.
For Polar Alignment you need to use the MENU > Alignment > Polar Alignment option after doing a normal 2 or 3 star alignment.
You then repeat by doing another 2 or 3 star alignment then MENU > Alignment > Polar Alignment until you get reasonable polar alignment error (which just happens to have the same initials but is not the same thing)
I can't say for sure but I can imagine that doing a PAE before the polar alignment could screw things up..
Another way to check where the problem lies is to use the UTILITY function > Show Position option too read out where the controller thinks your scope is pointed.
This mount does not have any encoders and uses the start position and number of steps it has taken to work out where it is. This is done in the Motor Control Unit (MCU) inside the mount. The handset asks the MCU how many steps it has taken and converts to RA/Dec.
The fact that the scope seems to be tracking OK after a manual PA suggests the drive hardware (motors and gears) is OK.
