Custom weather issue

Series X here on latest update

No matter what I try I cant for the life of me get custom weather working.

I have multiplayer off as well.

Presets are fine, but if I make a custom preset, and set to extreme cold or extremely windy weather, I load into my destination airport and there is no wind and and temps are average.

This might not be a bug but its an issue I cant seem to solve.

Can anyone help

Thanks
