Not wild but Researchgrade - is this a bug?

https://www.inaturalist.org/observations?captive=true&place_id=any&quality_grade=research&verifiable=any
Am i missing some part of the rules? How can Researchgrade observations at the same time be marked as cultivated?
Only if i add a second cultivated vote they turn Hobbygrade.

Thank you, that was quick.
The same problem occurs with other contradictory search parameters. Like searching for “Unkonwn” and “Researchgrade” gives 13554 results: https://www.inaturalist.org/observations?place_id=any&quality_grade=research&verifiable=any&iconic_taxa=unknown

Taxa that don’t fall within an “iconic taxon”, such as bacteria and viruses, show up under the “unknown” filter. For one recommended improvement to that, see https://forum.inaturalist.org/t/create-iconic-taxa-for-bacteria-archaea-and-viruses/1464
