This issue affects the Devices list view page in version 8.2 of the AirWatch Admin Console if enough devices are in the environment so there are at least two available pages. First, select the checkbox to select all devices. After this, deselect certain devices. Any bulk action that is then performed (such as query or device lock) will actually get applied to all devices in the list view, including the deselected devices.
This issue has been given identifier CMDM-195060. This issue has been resolved in AirWatch 8.2 FP02.
