You will find the official names as name:De_Lijn and name:TEC respectively (https://www.openstreetmap.org/node/2567895806).

The main name has been manually derived from the main operator’s name—this place is Wallonia, therefore TEC is the reference—but respects OSM conventions about multilingual names, therefore we use proper separator instead of mixing both languages as TEC does for its own stops.
