BMWorld&Amsim KSEA elevation problem

Does anyone else experience some weird elevation problems around the airport especially at RWY 34L and 34R? The TCH height of the ILS 34L and 34R puts me at around about 8ft above the runway threshold and some mild turbulence will make the aircraft hit the ground before the runway.

Did you disable the default KSEA? If not, try that.

I disabled it before I installed the BMWorld version. I’m not getting some super weird buggy terrains. It’s just that the glideslope doesn’t seem to match the runway elevation. This happens occasionally when 3rd party change the airport elevation but it’s just particularly bad to the point of being unflyable in this case.
