A UI Policy is configured to hide the section based on field conditions or user criteria, either through the 'Visible' checkbox being unchecked or script logic setting section visibility to false. (high likelihood)
The section has been removed from the form layout or form view configuration, making it unavailable for the current form context or user role. (high likelihood)
A client script is programmatically hiding the section using g_form.setSectionDisplay() or similar API calls based on form logic or field values. (medium likelihood)
ACL (Access Control List) restrictions are preventing the user from viewing the section due to insufficient read permissions on the section or its contained fields. (medium likelihood)
The section is configured with role-based visibility restrictions that exclude the current user's roles, or the section has conditional display rules that aren't being met. (low likelihood)
