That is very puzzling. I can understand why Mark had the problem since his AFX file for YMES has three 44 meter parking spots and all the welded AI formations that I have used are 41 meters or less, but if your welded formation is larger than any parking spot at the airport that you are having your welded formation flying the IFR missed approach into, how can your welded formation ever park there?
Have you tried creating a dummy airport with just a 500 by 1 foot runway ~140 feet below the elevation of your actual airport to fly your IFR missed approach to? That should eliminate the problem entirely since there will be no physical connection to the visible airport.
