It’s not just the browser or ICON. My screenshot of the app on an iPad (Version 46.0.4) shows the none of the wind vectors match what is shown in the tables below and neither do any of them match the “particles animation” shown on the screen. The “Display as Wind” view is garbage!

@idefix37 Yes, I agree it is very strange... but I can also reproduce it on multiple devices

The labels for "Observation vs. Forecast", 'Wind detail" and "Temperature detail" show up as "undefined" on the iPad app and in the Safari browser used on an iPad and Mac when displaying weather station data and when comparing models to weather station actual data. Also noted a similar error on the iPhone app.
