Unlink an incident from a test step

Hello,

I am executing a test case (with 40+ test steps) and accidently attached an incident to the wrong test step.  Is there a way to remove or unlink an incident from a test step?

In the incident, the Associations tab has the IN linked to the Test Run with status=Implicit.  I cannot select this association to delete, but I can select other incidents with association type=Related-To and delete it.

As a workaround, I am re-executing the entire test case which means I have to enter results for  40+ test steps.  Please advise if there's a more efficient way.

Thanks,

Anh
