Managing sceneries generates error, how to?

Hello,

I try to create the same scenery organization as I have in FSX :

a folder per continent , in that folder a folder with the airports (scenery end texture), a folder with the Landclass (scenery) , a folder with the Mesh (scenery)

With that organization I can activated the sceneries of the continent where I want to "fly"

BUT

When I try to add the airport scenery for the 2nd continent it is refused...

I do not know how to solve this ...

Any suggestions? recommendations?

Thanks in advance

SOLVED,

Mandatory to add some suffix behind the continent folder name

Example :

From "Asia" tp "Asia Add"
