Default Constant notification sound with cm11 m3

Recently flashed CM11 m3 and having a strange issue. It seems like unread emails (gmail app) are setting off a notification sound every 30 seconds or so. I'm not talking about new emails setting off notification sounds, its existing unread emails. If i swipe off the notification from the tray, they stop, until I get a new email, than continues with the excessive notification sounds again. I looked in the gmail app for a setting for this, but cant find it. I see an option to notify for each new email, but not continued notifications for email. Any ideas?
