Approved Change Order not Setting Status Correctly

Hello,

We have a project change order workflow that occasionally does not set the status correctly when approved.  I have attached screenshots that shows the issue.

The first two screenshots are of two different change orders.  You can see the status goes from Working to Submitted, then six instances of Submitted to Approved.  We have extended/customized the seeded work where it finds the next approver, because we require so many approvers for a project.  Six people approved the change order.

The third screenshot shows the status is at Working, when the status should be Approved.

I can view the workflow, and see that it went through our find next approver extension/customization correctly, then it calls pa_control_items_workflow.change_status_approved, which is seeded code.  The fourth screenshot shows that the status should go to Approved, and usually works correctly.
