2825221 - Error while updating Contingent Worker job history

We are currently facing an issues with contingent worker. When we try to change the job information record of a contingent worker, an error arise that the time information is required information:

1. Please assign a time recording variant so that all the Time Off fields have an entry.
2. Please assign a work schedule so that all the Time Off fields have an entry.

If we try to delete the record we get error as

'Please assign a work schedule so that all the Time Off fields have an entry.'
