I guess you mean connections when you say connectors. If yes, we prepared a test project based on your scenario. When you select an item the TextBlock on the right of the Diagram will display its type. We think the deselection works as expected when clicking on the diagram after selecting a connection. Could you please check out our test project, let us know if we need to change something in order to reproduce the mentioned issue ? Thank you in advance for your cooperation.
