Deleting a comment does not delete the vote

I am using Simple Review with Fivestar. When logged in as admin, upon deleting a user's comment their vote is not also deleted but instead remains active. This is not good because the total average of the users votes, which I display on the top of my product's page, does not equal the actual average tallied by the users' comments and users might think the rating is rigged.

There must be some way to delete a user's comment and vote at the same time when clicking the 'delete' link shown to admin at the bottom of the comment.

Please help,
Jake.
