When I run the verification for the certificates and every time you log into the appliance, I get a warning about this out of date cert, but it doesn't appear in the list at all,
There was an issue where deleted certs were being included in the validity check, do you find that if you “Check Now†at System>Configuration>Certificates>Certificate Validity Check it is listing a deleted certificate that is not installed? If so the fix is in 8.2R5 and later releases.
