SOTA ADIF upload - callsign suffix ignored

[oe9shv]

Hello,
happy new year - I did a SOTA activation and could manage to upload the log out of L4OM based on ADIF export.
I had the configuration station callsign with extension /P as well as operator callsign with extension /P.
However after uploading ADIF to SOTA DB the logged QSOs are shown without the suffix /p extension.

I expected, LOG4OM is using my callsign based on station or operater callsign. But it does not do so.
How can I influence that LOG4OM is exporting ADIF with my correct callsign extension.
I could not find the solution, would highly appreciate any hint on this topic

thanks and 73 Harry
