[NTG-context] \setupinteraction "author" adds '"'

Hello, once the "author" member in \setupinteraction contains ",", Ctx adds (unwanted) quation marks into "author" field in PDF. So - how to avoid these '"'? My MWE: ---- \setupinteraction[author={Foo, Bar}] \starttext A \stoptext ---- Result - see the picture. Best regards, Lukas -- Ing.
