I have been adding zones to a model for a SD set to illustrate area's being served by various Air Handling Units. Unfortunately i have gotten an error when i try to edit a zone. one specific zone doesn't allow me to select it or delete it. It states "Can't delete element that is being edited." Does anyone know how i can exit this mode? I know typically a modify zone tab will be available but i do not see one unless i choose one of the other zones i have already created. This also goes for new zones which i try to create.

I have also attempted to detach the file from the central to override any attempts in which anyone has possible gained control of elements and that has not worked either.
