Certificate device_cert_key.p12 is near expiration.....

Question

Is there a way I can delete a self assigned local cert so It don't have to worry about it expiring? I had created it for testing purposes.  When I tried to delete it using the common name "server.domain.com", it doesn't let me.
Certificate device_cert_key.p12 is near expiration. It is configured as machine cert in global settings

The factory self assign is not the one that has expired. It's the one that I've created for testing purposes. I figured out on how to delete it. Thanks for the info on the bug ID CSCte05426.
