BB Gmail Client Sends Multiple Copies to Recipient

I have gmail client installed, and sometimes when an email is sent, the person it is sent to receives multiple copies. When looking in sent mail from gmail, there are not multiple sent copies.

This is not the issue where duplicate copies appear.

Anyone know why this might be happening and how to fix?

I think that you need to adjust a filter in the BIS website so that it does not replicate sent mail.
