Up until two or three days ago, I had my list set up to do passive
probing. Every night for weeks, I get a subsciption renewal monitor report
that identifies the same set of seventeen subscriptions that are were
probed. I tried turning off the passive probing a couple of days ago, yet
the same seventeen subscriptions are still reported as being probed in
each nightly report. Why? How can I fix this?

My list previously had the keywords

* Auto-Delete= Yes,Full-Auto,Probe(4)
* Renewal=Monthly,Delay(4),Probe

but I changed the renewal keyword to

* Renewal=Monthly,Delay(4)

and left the auto-delete as is.
