Workflow Signing Limit [Expense report in Microsoft Dynamics 365 finance and Operations

Hallo

I am having an issue trying to create a Workflow using managerial hierarchy and signing limits.

I want to make a workflow with expense report functioning this way:

• Worker can approve anything up to 100USD
• First manager can approve anything up to 1.000USD
• Team Manager can approve anything up to 5.000USD
• Regional manager can approve anything up to 25.000USD

(I did this in Signing limit policies)

I made this hierachy with "report to" with postions.

• Worker report to FIrst manager
• First manager to Team manager
• Team manager to Regional Manager

I am using this in the worklfow

But it still doesn't work - Every time I add a Expense report to the workflow it will be assigned to the same person each time (Team Manager) - Doesn't matter if is 50 USD, 750 USD, 1500USD.
