KACE Product Support

We have been testing our service desk with a test gmail account and today we decided to link our existing help desk email account to our service desk. Once we changed the email, added user account and password and clicked save the service desk started creating new tickets. It looks like Kace is going through our gmail account and importing everything from all folders.  We use Gmail for our corporate accounts and have a K1000. 

Is there a setting we can change to only bring in new emails and not everything? We have over 20,000 items in that account and it is creating a ticket for every single one.

Thanks in advance for any help.
