System bypassing CCM approval and directly routing to Payables team after FS approval for invoices.

We have several invoices that have only been ‘assigned to’ one approver. System bypassing Cost center manager approval and directly routing to Payables team for approval. The invoices should be approved by both Cost center manager and Financial steward. Approval is being routed to FS but not CCM. It's currently specific to one particular Cost center Manager for different Cost centers. This started happening from January. Screenshots for the workflow is attached below. Please provide me any suggestions. Thanks in advance.
