Error messages currently manifest in different ways on wiki, and it is not always clear how to fix them, or that they even exist and affect outcomes.
1st example: red text in infobox display when the edit mode for a metric field appears normal (height of building). it is unclear how to fix, or what the problem even is.
2nd example: when you add a field in an infobox, the field will not display reliably unless you select a corresponding label in most cases. at other times, even adding a label does not guarantee that the translated field will display. label selection should either be required or be skippable, but either way we need to manage user expectations around what will display.
