Are you rebooting LM via UI? If you reboot via power cycle then the latest changes might be lost.
As for you previous questions - the possibility to edit existing devices is not meant to be a replacement for the main Modbus UI. It is implemented to tweak the profile instead of making a new device from scratch if any mistakes are found. That's why proper object selection is not implemented.
If you edit custom values for an existing device nothing will happen until you map a new object via main Modbus UI.
