Incorrect orientation of components in Footprint Position File (KiCad)
A big problem with position files is that there is more than one standard for the so called zero orientation of footprints. The official library uses zero orientation standard A from IPC-7x51. Simplified this means pin 1 is always at the top left corner.

There are other standards. For example the orientation B from the same standard that places pin one on the bottom left corner.

The situation is even worse regarding component orientation inside the tape. Typically it is however the responsibility of the board house to map the PCB zero orientation to the tape and then the machine zero orientation (tapes can be fed from different sides relative to the PCB orientation inside the machine)
