Sorry for the trouble! This behavior means that Mail is running the rule, but has decided that it does not need to run the script that does the bulk of the work on the email in question for some reason.

There's as existing thread with some good tips which can be used when troubleshooting this situation; I'll move these posts to that thread in a moment.

If the ideas in the new thread don't get the mail rule working as expected, contact our support ninjas (800.315.6664 or omnifocus@omnigroup.com); we'll be happy to investigate this with you.
