Extension Period Units not visible during Employment Contract extension

When extending an employee's Employment Contract, the Extension Period Units field is not displayed.

We would like this field to be visible to users during the contract extension process. However, we have checked the page configuration in VBS, and the field is not available to be configured or set as visible.

As the field is expected to be visible by default, we would like to confirm whether the current behavior is a product issue/bug.

The issue was observed in 26B and is still present after upgrading to 26C.

Could you please confirm the expected behavior and whether this is a known issue or if there is any available workaround/fix to make the field visible?
