SQL Server Verification DBCC CheckDB finding errors on backup that do not exist on live database

Backup verification report has been finding consistency error in one database for the past week:

These errors started 12-18 and occurred during every daily backup verification except on 12-19 and 12-26. When I run DBCC CHECKDB on the live database, it finds no errors. Why would there be errors on most of the backups but not on the live database? What can I do to fix this?

Thank you!
