Wrong cells orientation

[EpSilicon]

Hello, I'm trying to generate a padring using the sky130_ef_io cells. The config file and the LEF are here: https://github.com/EpSilicon/OpenSource_IC_Design/tree/aaac67b832ec428b2b9f9427061800a5e8412f54/sandbox

The generated DEF shows a wrong orientation of the corners and the pad cells.

Is the issue coming from the LEF, the config file, the tool or may be something else?

Thanks and regards, Erwann
