Backup Exec 2012 Data Expiration Date

We are running BE2012 on Windows Server 2003. Based on backing up to harddrives, my backup sets are all set to expire in 5 days. There are numerous backup records that have the backup sets where the System State, Shadow Copy Components, and one of my data drives, have an expiration date of 1/18/2038! Why is this happening and what setting should I verify to correct the issue?
