Manager Hierarchy Issue in Administer Employee of Manage Alternate Approver

Issue regarding the Alternate Approval Configuration in the Workforce Compensation Plan.

Please note that there is a business requirement to create separate templates for legal entities under one division. Therefore we did a feasibility analysis on having a worksheet manager and an alternate approver on the manage alternate approver table for one division.

I have configure my WFC plan and for the plan hierarchy it is using FF from a UDT. In the alternate approver table, I have configured a worksheet manager and an alternate approver.
But in the manager Hierarchy of the employee shows a manager who shouldn't be eligible to view the WFC plan or edit the plan which means it has provided unwanted access for the user to access the plan.
