scenery behaving strange.

Hello, before anything im not sure if this post belongs here, if not opologise.
I have the Aerosoft Lisbon x (fs9 version).I instaled the scenery, and all went well ( i have to say that this is a fresh fs9 install, and it was the first time i install this scenery). But when i run the scenery i see all the buildings but the taxi ways i only see the yellow lines but no tarmac its all grass ( i know also, and its not installed, that this scenery is compatible with many land mesh)
I also have several "Mega airports" from areosft and all are well.
Any ideas??
Thank you very much
