Who's fault!

Have an issue with VTSM Samui airport. All the info is in navigraph. All the info is in simbrief and in the fenix nav data
But (I have an addon scenery) it does not appear on the world map!
Actually you can make it appear by searching for vtsm and all the usual parking and rwy are shown and selectable. But MSFS now thinks they are water rwys and water parking spots!
Probably not flown from vtsm for a couple of months but all used to work fine (including the addon scenery).
Anybody got any suggestions!
