Employees are able to submit timecard with holiday hours, but the associated time type is missed

We created public holidays in Manage Calendar Events, project, and overhead holiday time type. We added Project Holiday in the Worker Time Processing Profile.

The holiday hours are being auto-populated without a time type, and employees can submit the timecard with a blank project, task, and time type fields. Is there a way to restrict employees from submitting the timecard when there are only hours in the timecard?
