Oh, this is an interesting case here.

Houses on both sides are on different municipalities and, despite there is just one street, each municipality names it differently.

We have a few cases like this in Belgium, which we solve by using a compound name + name:left and name:right.  Addresses, though, only refer to one single street name, depending on the side.

Your picture is very clear and that house is
addr:housenumber=267
addr:street=Rue des Déportés d'Havinnes

Fixed, thanks for reporting.
