I can confirm the mount was pointing to the east, before reaching the meridian. In fact, before slewing to an object, at its home position, the time to the pier flip is reported. This issue is present after slewing to an object on the east.
If I slew to the west, the Time to pier flip increases!! As if it was pointing to east.
After both of your posts I selected “Reverse E/W” under the telescope tan in Control panel, but I found the same behavior.
