Hello,

Please inspect the list of tags here:
https://www.openstreetmap.org/node/6716272356/history

You will find that the website and phone number were already in the database.

I think the problem comes from the iD editor you are using.  If you only look at the presets (upper part of the screen) it will hide some information from you and fool you into believing data is "missing".

If you want to use iD, it is always better to type the tags directly in the tag list, at the bottom of the window.

Hope that helps.
