Hello! It seems to be a draft edit that is not yet in the main spec. I found a mention of this field here: https://datatracker.ietf.org/doc/html/draft-ietf-dmarc-aggregate-reporting-13 Since this field is already being used, I'll make sure it's at least ignored.
Fixed with db11fc89062ed379df1c8d0a02d96e4f9295d119. Thank you for reporting.
Maybe some speciality of web.de or new dmarc field
