It could come down to the AIRAC you use. If you update them from Navigraph every month, like I do, then the problem seems to increase as the newer AIRAC's are changing. I mostly have the problem on runways with a designation of X, Y or Z (i.e. ILS34LX, ILS34LY or ILS34LZ). These are getting more common every month, so the problem is increasing (for me) in the 757 & 767. Since the release of the 777 v1.2, it is less of a problem in that aircraft, but it is still there. So Captain Sim are aware the problem and are dealing with it (at least with the 777 ;D).
