ASI Air Plus Weird Calibrating Graph

[KYSTARS]

Last night when I tried to calibrate near the intersection of the celestial meridian and celestial equator, I kept getting this weird graph. I eventually just calibrated on my target M81 and doing that I got the usual graph with the 90 degree intersection. Anyone know what would cause the weird graph in this photo I have included? Thanks!

What mount ?

ASCOM or ST-4 guiding ?

The Calibration graph suggests that after completing the RA West/East steps, the North steps were in the RA direction.

A faulty ST-4 connection that cleared after slewing to M81 ?

ASCOM guiding. I have never tried ST4 guiding before. I guess my USB cables running between ASI Air and my EQ6R and also my guide camera could be bad. I bet you are right and there was a cable issue. It sure seems like one. I probably should switch those. Thanks for letting me know.
