Restore only presents 5 days to choose from. There should be more history.

I am needing to restore a SQL database from 3 weeks ago.

The job definition shows that the database is doing a Full backup Saturdays and Differentials rest of week.

Transaction logs are set to run 12x/day.

The job history shows successful backups have been occurring.

But the problem is that when I go to restore that database via the ‘Restore’ process, when I select the option to choose “A backup set time that I select”, I only have the last Full backup available from this past Saturday as a day presented as an option to select. (And it shows diffs and transaction logs for only  last 5 days)

Screenshots provided showing that older backups were performed and successful and should be available.
