Problem identifying brownfield sites - OSM

[EmmanuelleKerjouan]

I'm working on a bbox around Paris --> coordinates 4326 : 48.786057, 2.217522, 48.918213, 2.479820
I noticed that in some industrial zones, objects identified as brownfields were not classified as LCZ 8 (large buildings/industrial buildings) but as residential zones (LCZ 2, 6 or 9).
Here are the coordinates of the area in question : 48.803946147, 2.393004886, 48.820093681, 2.420028584


(LCZ classification produced with Geoclimate in early December)
