Reinstate programming flags if a user clicks Undo

1. Have fully downloaded device (all flags ticked).
2. Edit a single parameter on the device.
3. 'Parameter' flag becomes unticked.
4. Click 'Undo' to undo the parameter change.
5. 'Parameter' flag remains unticked. This is not correct.

Please fix. A device download is unnecessarily the only way to resolve this bug currently.
