One Identity Failing to abort expired requests

We are seeing expired requests (ValidUntil < current date) in the PersonWantsOrg table that are not being aborted by the db queue. We found that this is working as expected in our development environment but not in our staging (QA) environment. We attempted this solution:

But it did not resolve the issue. Has anybody else encountered this issue before? What was the solution? Thanks!
