Wind speeds are doubled, changing directions rapidly, i can't fly

Sure here’s a capture of the weather configuration with a single layer starting from ground set at 330/15 and showing on the ND as 330/30. I am using only US (hopefully :wink: settings. I am pretty sure it’s all in US because air speed is really in knots (would not be flying with this configuration is it was 222 km/h).

Thanks
