DVD/Blu-rays being marked as adult products so ineligible for sponsored ads

Another seller is persistently marking certain DVDs and Blu-rays as adult products which is making them ineligible for sponsored ads. These are mainstream commercial films and tv shows, NOT adult ‘shows’, and most are not even 18s, so there’s no way they would be considered adult products. One was a Star Wars Blu-ray for example.

I can only think that this seller is marking these as adult products purposely to prevent them appearing in sponsored ads. Would this not be a policy violation? Has anyone else come across this before?

Just persuade amazon that the classification needs changing.
Could simply be a mistake.
