Unable to hide fields from Update Requisition Preferences on Requisition page

Summary:

Hello,

On the Requisition page, when clicking on More Tasks and Update Requisition Preferences, I have as requirement to hide the fields Requester and Deliver-to-Location.

When using Sandbox, I am unable to find these fields so that I can uncheck the Visible checkbox with Page Composer.

Is there any workaround so that I can hide those 2 fields?

Thank you.
