ok...i've moved one section at a time in front of General (1) and the changes to entries correctly update for each section that i move above General (1).
renaming sections have no effect.
also, starting fresh, in the order of the original xml - if i copy General (1) and paste at the end and then delete the original General (1) from the top all sections also update when changes to entries are made.

one other thing, no matter which xml i try, after changing an entry in one section, as soon as i switch to another section the error message noti displays at the bottom but everything still works ok

hopefully this helps. i think you're getting there
