B) The changes do not back-propagate to the original nested element file. C) If the "raw" nested element file is opened in isolation, changed and saved, all designs that use it (like the above example with the locally-saved changes made to the nested element) have the placed (and maybe edited) version of the nested design replaced with the new updated version of the raw nested element. In practical use, that means never edit a Nested Element in place (using Open Nested Element) after it has been placed in a design, or you risk having those changes lost if any changes are subsequently saved to the raw Nested Element file and then you reopen the file containing the (edited) Nested Element.

The other 2 options behave differently, with "Load global and save" the changes you make do propagate to the original nested design. With "Load Global properties" nothing is saved except chart relative position.

Restarted design and it had reverted to the default. Is this intentional? Also, when set to Load Global and save then Opened and made changes, the changes didn't propagate to the source nested element. Finally, when opened as Load Global and save and tried deleting a connection line the Opened Nested Element closed. The only real way to edit the source Nested Element was to Load it.

The properties can be saved in the "Open Nested Design" dialog or from the design directly. The "Load Global and Save" option is sometimes used like a global variable between designs which load the same common nested design and need to keep track of changes between them. To fully edit use the "Load Nested Design".
