Did you remember to save the ini file after sorting it?
Do that then run Xplane until you get to the continue flight or start new flight screen.
Quit Xplane from there and recheck your ini file
If anything has moved rearrange it as it should be and restart Xplane, your ini file should now always stay in the right order.
Always repeat this process when you add new scenery.
I have attempted to reorganise your ini file for you but I don't know what some files are, whether airports or mesh or photoscenery. I would have assumed your "zzz" prefix named folders are mesh but some seem to be airports?
Frankly your ini is a complete jumble and mess, I doubt half your scenery worked correctly anyway. You seem to have some libraries duplicated as well such as Mr X library,
The order for your scenery ini is as follows from top to bottom.
Xplane landmarks.
individual Airports (such as Orbx Barton)
Global airports
OrbX scenery other than airport.
OrbX overlay folder
Libraries
Scenery folders
ortho scenery
Mesh
Remember what is above on the list will suppress what is below.
Put the ini I link to in your custom scenery folder and follow the instructions I have given and let me know.
Frankly though your ini file is in need of serious surgery.
