All reservation agents disabled, still repeat notifications being sent

The reservation notification of approval agent has been disabled in early December.

I did a test today on a resource and no notifications for approval were sent, works fine.

Someone modified an existing meeting from October and at 2 AM the approvers got a slew of notifications for approval?

can anyone explain this or offer ideas on how to fix this?

thks,

PS the resource reservation db has a replica on 2 servers.
