Amazon have notified me of a Restricted Product Policy Violation for the DVD comedy "Personal Services" Starring Julie Walters (1986)

We sold one of these over 4 years ago and have now deleted the listing, but Amazon have stated that it has been identified as one that is prohibited for sale or violates image guidelines, and that they prohibit any sexual or offensive adult product or any listing(s) that may include explicit sexual imagery. Having said that, the film is still available on Amazon in 5 other DVD releases, so it appears that Amazon's automated bots are overreacting and highlighting a problem that obviously doesn't exist. I would appreciate any suggestions on how to deal with this.
