Learning Request page: Need to make Start Date and End Date required fields - not working in VBS

Hi everyone, I'm trying to make two seeded fields on the Learning Request page mandatory:

• Learning Request Start Date - does not come up as required (other DFF fields shown below afterwards are working ok)
• Learning Request End Date - does not come up as required (other DFF fields shown below afterwards are working ok)

VBS Field Rules:

VBS changes applied in App Extn Preview:

Version (include the version you are using, if applicable): 25C
