Auto complete rule is not working as expected

Summary:

We have raised one case for Auto Complete Rules at the create requisition page, but despite of the approval of that auto complete rule, the same field is not working as expected while creating the requisition.

Requirement: There are 9 list of values for one of the field(Requisition Classification) under Create Job Requisition page. Among these 9 values, Each three values belongs to one Legal Entity. While creating the Job requisition, whatever the Legal Employer we choose under Requisition Structure-->Organization, based on that legal Employer, three values needs to be displayed from under one of the Job Requisition DFF(Requisition classification)
