I am having the same problem. After doing a complete reinstall on W10 I downloaded X-Plane 11, once loaded I was able to customise the weather through the icon but now it has stopped me accessing into it. I can use the slider but unable to change wind direction or strength, I have gone through a number of options including removing plugins, removing the preferences folder and restarting X-Plan 11 and only once did it allow me access and that was whilst on the ground in the aircraft, after that it would not let me back into the customisation section. Time of Day works fine.
Can anyone advise on this please?
Regards
Nigel.
