It looks like amenity=fuel was already set before your edit, you just changed the building value to "yes".

Which building value should be used to specify that it is a fuel station building (in the case it's not longer used as one, (in the one you changed it's most likely a roof (with just looking at osm carto, so don't change it based on my comment, i just wanted to say that my question is not about this specific fuel station)))
