Hello.
You've broken some topology between the railway station indoor data and the pedestrian area near the exit https://www.osm.org/node/4086595159. I have just fixed it with https://www.osm.org/changeset/135967342.
BTW : Bing imagery is not the reference in France, please use the BD Ortho imagery provided by the IGN, and beware of parallax on high buildings.
Regards, Antoine.
