How do we remove IRS Lock in Date from Redwood Calculation Entries Tax Withholding page?

We could use assistance with the Redwood Admin Tax Withholding page, in determining how to remove the IRS Lock in Date from employees who have them.

To attempt to do this, using the Redwood Calculation Entries page, we opened a Federal Tax Withholding row with an existing IRS Lock in Date, then removed it and clicked the Submit button. This resulted in the error shown below.

'Provide the value in the YYYY-MM-DD format for ORA_HRX_US_FF_FIT_LOCK_IN_DATE.'.

Steps to recreate:

Navigate to My Client Groups > Payroll > Calculation Entries > Choose a USA employee > Click 'Tax Withholding' > Click the Federal tab > Click the Actions (Ellipses) on right-hand side and choose Edit > In the 'When does this change start?' box, enter a date > Scroll down to IRS Lock in Date and
