rkilian Calibration starts stepping in one direction, but it does not reverse in the opposite direction.
I wonder if this "one directioness" is caused by calibration step size being too small, or tracking was turned off.
In one East-West direction, the stars will move even if you don't apply calibration pulses (due to the sidereal movement). In the opposite East-West direction, you need to apply a large enough calibration pulse to overcome the sidereal motion and more, if tracking is not on. For example, if tracking is off and you only apply 2000 ms at 0.5x sidereal rate, then you are barely just keeping the star stationary, instead of moving it.
Try first checking if the tracking was somehow turned off, and then experimenting with increasing the calibration pulse duration to at least double what you have set if it is not at a missing tracking problem.
Do not depend on the tracking on/off state shown by ASIAIR. Look at the tracking state on your hand controller.
Be sure to also set the slew speed to 1x (slide the slew slider to 256x, wait a second, then slide it back to 1x, just in case), since there is another bug in ASIAIR that causes it to use the slew speed setting instead of the guide speed setting (ASIAIR had tons of bugs like the two already mentioned). This one is mentioned in the text instructions in the first guide window when you initially switch from the main window to the guide window.
