Where are the "Approve Job Requisition" OTBI Notification templates stored?

With our recent activation of all available Redwood Recruiting pages, we've started to see "Approve Job Requisition" notifications start coming in where we previously did not. They appear to be OTBI templated notifications and NOT stored in Alert Composer - does anyone have any direction as to how to reach them and/or disable them entirely? We do not have approvals for our job requisitions (nor have we ever), NOR have we enabled the new Approvals page. We're perplexed as to what these are, where they're coming from, and how to kill them.
