OK, understood, but they don't appear for the hundreds of other entries. That to me indicates something amiss.
I seem to be having a lot of trouble explaining things clearly to you. I have not mentioned runways.txt anywhere!. I have been talking about the generated file F5.csv which is read by the PFE software. I am aware how AFD files work through the scenery layers - this works fine in Flight Simulator but gives this problem in the F5.csv file when generated.
The file is now on its way to you by email.
I am not misunderstanding any log as a control file. I am simply notifying you of an issue with an imprefect AF2 file which, as I said, you may wish to deal with or equally you may feel it is up to the user of add-ons to ensure they fix or discard them.
Many thanks,
John
