Preconditions

1. Clean Magento 2.4

Steps to reproduce

1. Set Customer Date of Birth optional or required in Customer Name and Address options
2. Save Configuration
3. Go to Checkout (after clearing Cache etc.)

Expected result

1. Field for Customer Date of Birth is displayed in Checkout

Actual result

1. Customer Date of Birth Field is not displayed in Checkout
   
   

Additional Information

1. For all the other fields, except for Date of Birth and Gender, these settings work. If a value is optional or required, a filed for those values is displayed in the Checkout View (like Phone number, Prefix, Suffix etc.)
2. In Magento 1.9 this worked perfectly. If the Date of Birth was set optional or required in the Customer Settings, the field is displayed in the Checkout View
