Dashboard not working - date fields changed to epoch format

[AliciaShyu]

Dashboards not working after geodatabase upgrade to 10.7. Everything else (services, applications, web maps, etc.) are all working without any issues after the upgrade.

This specific dashboard has updated date and created date fields both are showing in epoch format in the dashboard only. The date format is correct everywhere else except on the dashboard.

The indicator widget on the dashboard doesn't work because it can't filter by the date due to the new format.

Any ideas?
