Keywords on an episode of Yellowstone rejected.

Four keywords were rejected when I originally watch and episode of Yellowstone called Blood the Boy with a rejection of "Reason Not specified". The second time I submitted them, "reference-to-harvard-university" was accepted but the other three were not. None of them seem controversial as they are "hunting", "killing-a-deer" and "dead-body-in-trunk". Can a staffer look a see why these were rejected as they seem valid to me.
