I did some corrections in this area in the last days and moved house numbers before seeing your note.

Since you created the note from Organic Maps—which does not read real-time data but uses monthly exports—I suppose your first note relates to the former situation.

The good news is that your suggestions match what we had already changed to reflect UrbIS data.  The only exception is this building here: https://www.openstreetmap.org/way/260917331 (you can see it here: https://www.mapillary.com/app/?pKey=1633762723670617).  It is numbered 15 on official UrbIS data provided by the Brussels Region but I cannot see a number here (it is very logically between 13 and 17).

I don’t know how long it will take for Organic Maps to refresh its data and offer a new set of data to download, but you can check on osm.org, where tiles are updated after a few hours.
