BPM Worklist -Task configure (FinApInvoiceApproval) Setting up an auto approval rule for 1 supplier

I'm trying to create an auto-approval rule for a single supplier's invoices to eliminate the need for manual approval. I've set up a rule with specific criteria, but the invoices aren't being auto-approved when submitted.

The above picture (from Transaction console) shows the invoice after being validated and initiated being assigned to various managers; instead of going straight to workflow for auto-approval.

The above picture shows(Transaction diagnostic) the rule is active in the system and the invoice is now assigned to a person instead of workflow auto-approved. Is there any way to trace the exact path the invoice took for the approval process? Is there anything incorrect about the rules configuration?
