I’m sorry my friend I understand as you say except how to create a new one , and I what you mean address scenery\world\scenery

Open the scenery library and if the Default Terrain entry is missing, select add area.

Navigate to your P3D\scenery\world\scenery folder and give the new area the name "Default Terrain.

It will be placed at the top of the scenery library.

Click once on "Move down" and then hold down the return key until your new area reached the bottom of the list.

This is what you should see at the bottom of your P3D scenery.

And it will go up to folder 1107, if the 2 base folders get corrupted you will not solve the elevation issue as they are ground zero for the sim an airport with elevation + or - will take it from that.

I highly appreciate your support my friend, I will be home in one hour, I will follow your advise and report you back. 
thank youuu

Hi, may I ask you, why the numbers start from bottom going up? I know my base numbers are numbered from top to down

Hi, both scenery and texture default exist at the bottom of Addon organizer also Base numbers correct. I uninstalled all Orbx products again, I started p3d and unfortunately the problem exist.

to reinstall p3d with all the add ons and scenery I have it should be a nightmare and take me a month.

What else I can do I don’t know.

i should attach some photos here but I have no idea how so you see how it looks

Screenshots of your Scenery Library would be useful, showing the order in which your scenery packages are arranged.

Can you post your scenery.cfg here?

First time happens to me this, never experienced this issue. Thought reinstalling 

client, content even scenery should resolve it but NOT.

Always knew that running Make Runways or Orbx elevation correction resolve those issues but so it happened.

if it helps this, because I needed  to install MSFS 2020 and didn’t had enough 

space on my SSD I deleted Orbx folders without to uninstall Orbx products from the central.

Maybe helps?

Copy the Terrain.cfg to your desktop for safekeeping and delete the one in the folder and start P3D, see if that fixes the issue.

Where this file is located please?

The scenery files are not on flicr but it might be that scenery areas are not in the correct order or the shader files need to be deleted.  Browse to C:\Users\User Name\AppData\Local\Lockheed Martin\Prepar3D v4\Shaders and delete the .cso files in the folder only, do not delete the folder.  Restart P3D and launch a flight and let the scenery load up.  Be sure not to load a saved flight, use the default then go to the airport at which you were earlier and see if the issue is resolved.
