The 67 is within the 609 who qualified, not in addition to. So if you were to send the email, it would only be sent to 542 Leads. You can also click the 69 excluded to see the list. You can create a view that includes Unsubscribed, Marketing Suspended, and Email Invalid to see why those 67 are being excluded.
Similarly, if you were to add the filters for Unsubscribed, Marketing Suspended, and Email Invalid in your smart list for your campaign and set them all to false, your schedulle tab should say 542 qualify with 0 excluded.
