L3A Processor manual mode: product specification xml?

Hello,
i am testing the sen2agri for the first time and after uploading a site via web interface i am trying to start a L3A processor job with this site. However the mandatory ‘list of products descriptors (xml files)’ is empty, I can’t chose anything and I don’t understand what this should include from the user manual - so I also can’t figure out why there is nothing to chose…? Did I miss something during configuration?

regards, nina

problem solved. The data download wasnt finished. regards nina
