If the Cinegy Studio layout is configured to work with specific devices, only items assigned to those devices will be visible in the Rundown and on the timeline by default. However, you can adjust the display to show only particular devices by using the "Device" drop-down list, narrowed to display only relevant devices:

Rundown_panel_select_device

Only items assigned to the selected device will appear in the Rundown and on the timeline, while Stories with no items assigned to that device will be collapsed.

To also display items for inactive or unconfigured devices, enable the "Display all events" option in "Preferences".
