[atlas] how to delete a never used software probe

Dear All, by a mistake I submitted the wrong SSH key during the installation of a software probe. Therefore I have now in my list of probes a second probe ID which is hidden and was never connected. Querying the Internet tells me Click on your probe  and Click the "Write off your probe" function on the probe's detailed information page But when I do so I see an almost empty screen with the probe ID and "This probe was Never Connected" and nothing else. Any help is welcome. Kind regards Hans --
