For those who use the EKVG airport scenery (downloaded from here) and Navigraph Navdata, there are two overlapping, though slightly misaligned, runways. I am using version 1.5 of the scenery, the latest to date. The issue was present in Cycle 12, possibly also 11, although I am not entirely sure, and is still present in Cycle 13. The issue is not present when using the default MSFS navdata.

Navigraph Cycle 13 (Beta) Navdata:
The author of the scenery claimed in a comment in October I have read that Navigraph will solve this problem in their next release. Other users have reported the same problem with other airports too. There’s nothing I can do unfortunately. For the moment I guess you will need to turn off Navgraph to use this airport.
I am unaware of this happening at other airports.
I am also unsure if this is an issue with the EKVG scenery itself or with the Navigraph data, but hopefully, this can be investigated.
