Requisition - Conditionally hide or display field using Page Composer Expression Builder not working

Summary: Conditionally hide or display field using Page Composer Expression Builder not working during Requisition Checkout and Submit

Content (required): We are trying to conditionally hide or display the "Suggested Buyer" field in the Requisition Lines based on a DFF attribute10 value (Y/N). We have created a Sandbox with Page Composer tool, then navigate to Show Component and then opened Expression builder and written the following #{bindings.Attribute10.inputValue == 'Y'}

However this is not enabling the Suggested Buyer conditionally. this field is always disabled. Please let us know what we are missing. Any help will be appreciated. Thanks !
