Click the menu button to the right of the label that you want to remove and select Delete. Or, to delete multiple labels, select the labels that you want to delete and from the menu that appears at the top of the list grid when you have selected two or more items, select Delete.
The Delete Connector Label dialog opens. If the selected label is used in process diagrams, a list of places where the selected label is used will be included in the dialog. Optionally, you can download this information in Excel format by clicking the Download Where Used Report button.
