Сценарий Powershell, выполняющий оба пакетных файла, когда выбран только один элемент списка

Question

Первый l oop правильно подхватывает все сервера. Я считаю, что разбивка связана с вложенным l oop, который доставляет $ listBox.SelectedItems. Я выбрал только OPENFIRE, но он также остановил JBOSS. Я изучаю PowerShell, поэтому приветствую любую помощь, которая поможет мне понять, почему это происходит.
