Mailwasher remove downloaded emails

[Allegra]

After I download and read my email on Windows Live Mail, Mailwasher used to automatically delete those downloaded emails from MailWasher when I clicked Process Mail. However, it no longer accomplishes that task. I have to highlight all of the emails in Mailwasher and press C in order to delete the emails from MailWasher.

Question: What setting on MailWasher do I activate in order to delete these emails automatically when I press Process Mail?

Thank you for providing any assistance you can offer.

MailWasher only knows the emails are gone next time it checks for messages, a regular Check Mail or timed check should clear those.
