The issue you are describing was fixed very recently and honestly our CDN might still be caching the older copy.
I just issued a purge of the entire cache on our CDN. So if you try again after instructing your browsers to purge their cache, the issue should be fixed. This also fixed the station name (basically everything you are describing).
To verify the station is correct simply open the map. It should show the same GPS coordinates as the station. Weather Underground will resolve the coordinates back to your station every time.
Update: Also, please note the station pins are not told to be shown when the zoom level is very low (viewing the whole country, etc).
Update 2: Again, the apps are still affected but an update will be pushed soon to resolve it there.
