The following is true for any type of attached files. I will use Excel for my examples...
Case 1: Paste ANY.XLS from outside EN two times to a note and rename one of them to NEW.XLS:
Bug: Both copies of the file will get the new name NEW.XLS
Bug: Name change of the other file will not be seen immediately (ANY.XLS seems to be active...)
Case 2: Paste ANY.XLS from outside EN to a note and rename it to NEW.XLS. Then paste ANY.XLS a second time to your note.
Bug: Second copy will get the name of the (renamed) first one (both are seen as NEW.XLS)
Case 3 ("combination use case"): Cut&Paste an already attached file ANY.XLS within a note, rename one of them to NEW.XLS. Double-click the renamed file NEW.XLS to edit its content. Exit Excel to save the changed file.
Bug: EN shows the unchanged file ANY.XLS as NEW.XLS (false) when changed file NEW.XLS is re-imported.
Bug: Both files do have the same content. Original content of ANY.XLS is lost.
