Multiple copes of email received

I am connected to a Gmail account. Every now and again I start getting the same email from Gmail over and over,. They come in as already read so they don’t trigger a notification. I’m not sure if Gmail is sending over and over or if emClent is just duplicating the message. I have setup a filter in Gmail so that these emails are deleted in Gmail and should not be received by emClient. Any idea what the problem might be or how to troubleshoot this>
BTW, my version is 8.0.3385

Thanks,
Mike
