Terminate an instance in 'undefined' status

Hi

I created an an instance using the Fiori UX Demo solution, which created the Frontend in AWS but got an error on the backend end from Amazon awaiting approval of my account.   I emailed AWS and they informed me of approval.  There were no changes in the status of the CAL so I decided to terminate and start over.   When selecting Terminate, the message indicates the instance is terminating but it never removes the entry from the CAL instance list.

When I look at my AWS account the instance was actually terminated and subsequently deleted (the frontend server).

The user is P1940881394 - could someone please remove this entry so I can recreate the instance from the solution ?

thanks

Peter
