There are double windsocks at FSDTKEYW and is incorrect. Screenshots attached
That's an interesting issue.
We don't have any double windsock in our scenery, the 2nd one you have is coming from the default scenery. Problem is, the default scenery *before* the latest US update, had the windock in a completely wrong position, on the other side of the runway, so we made an exclusion area center exactly around that, to remove it.
Now, it seems with the US update, the winsock has been moved to a more correct location, so it looks like a "doubled" one, since ours was already in the correct location to begin with, but of course our previous exclusion is now outdated.
Just run the FSDT Live Update to get the fixed file.
