How to stop the listener in SoapUI after running a test case with a test step that is a mock?

I am running the test case **AT_retry**, which has a mock as a test step called **at** (executed after the step indicated in the **Start Step**). The mock **at** correctly captures the request.

Then I run another test case **AT_positive**, which also has the mock **at**. This one, however, does not capture the request because SoapUI does not stop listening on the mock **at** that was started in the first test case, even though the test case **AT_retry** has already completed.

How can I force SoapUI to stop listening after the test case ends? Currently, the only solution is to restart SoapUI.
