I'm working on Israeli air base of Hatzor, LLHS.
There is something, probably coming from the fs9 default airport, that I'm not able to eliminate.
Here you can see the def airport

In the red circles what I'm referring to. They seem to be apron, but they are not present in the default afcad here below

I've created the exclude files with Sbuilder as usual, excluding after many test, all the layers from 1 to 20, but I can't solve the problem as you can see below
My Afcad, exclusion polygons were added successively, notice that two apron are smaller and one was not drawn

Here the airport in FS9

Someone can help me in this?
I've already deleted every LLHS file coming from IAF package and don't have any other AFCAD for this airport.
Thanks in advance, Giorgio
