Hi Bernie,
Thanks for the files.
Good news and bad news.
Good news is I was able to recreate the problem.... bad news is there's nothing I can do about it although you may be able to. I don't have the Aerosoft EGLC so was unable to try what I'm about to suggest.
Now, the issue is EGLC is actually missing from all the relevant MakeRwy files you sent me for some reason. But my guess is this.... The way I believe the program works is it scans the scenery.cfg file and processes each scenery item as it finds it. Assuming that should it find a duplicate that any previous entries for the same airport can be dropped and the subsequent entries retained for the final file creation.
So, according to your runways.txt file it finds the default EGLC as indicated here:-
Airport EGLC N51:30:18.9957 E000:03:18.9995 19ft
City Name="London"
Airport Name="London City"
in file: Scenery\0601\scenery\APX48130.bgl
It then continues and further down the list it finds the new Aerosoft EGLS as indicated here:-
=============================================================================
Area.159 "London City Airport X)" (Layer=157)
Local=Aerosoft\London City Airport X
=============================================================================
Aerosoft\London City Airport X\scenery\EGLC_ADE_BR.BGL
=============================================================================
Airport EGLC N51:30:18.9957 E000:03:18.9995 20ft
City Name="London"
Airport Name="London City"
in file: Aerosoft\London City Airport X\scenery\EGLC_ADE_BR.BGL

COM: Delete all frequencies!
If you notice the DELETE entries which is where I believe it removes the previous entries read into its internal tables. Normally this works just fine, because most of us have added replacement airport sceneries, etc. But further scanning of the runways.txt files finds further entries for EGLC as shown below:-
=============================================================================

As you can see in the above example the entries marked for deletion, which I assume to be the last entries read for EGLC.
Now this is purely guess work on my part as I have no idea how MakeRwys actually works but what I would suggest is to either remove the entry for this BGL file (not sure why you need it anyway, and see if that works or deactivate the original EGLC from the scenery.cfg file so you are left with just the Aerosoft one. Again not sure if that will do the trick.
Failing that, or anything else you could try, I'm afraid you will have to report this to Pete Dowson... in fact I think it should be reported anyway even if you find a workaround because it is clearly not working how I would expect he thought it would. I can't do it myself as I don't have the scenery in question and Pete may well ask for a copy of one or more BGL files to aid his problem resolution.
Hope that helps and please let us know here how you get on
