news article not posted under relevant show

This is a bit annoying. How is it that a news story regarding a specific DC Universe show (https://www.imdb.com/offsite/?page-action=offsite-wegotthiscovered&token=BCYquP1nZkATwoqsyuk6tNa...) will show up as 'Related News" for seemingly every other DC Universe streaming show except for the one that is the actual subject of the story, i.e. Harley Quinn (TV Series 2019- ): https://www.imdb.com/title/tt7658402/?ref_=rvi_tt? If this was just a one-time thing, it wouldn't bother me so much.
