Exim Configuration Changes Don't Seem to Stick

I made changes to Exim configuration to add a whitelist, some directives were added and modified in the first and middle box, and then saved.
However after reviewing the config boxs the changes to the first box seem to have been retained, while the changes to the other box of overrides were lost.

Is this a normal behavior, or should I see my config changes?
Shouldn't my changes be sticky?
