I'm having the same problem with my FS, 2018 model. When runs into the point to switch tracks the front boggie derails. In another point, as it pulls out of the station, again the switch tracks, the front boggie rides over the point, derailing and also changing the point direction. This is a new setup, just got the track sorted and testing it. The points are 1st radius, was wondering if I changed then for 2nd radius express points if that would fix the proble. The engine goes over the other points with out issue, but they're not set mother than to go straight on.
