Thanks for the pictures. We need some coherence here and globaly for this kind of case. 

V1 and V2 has the name as given by urban brussels and used as i indicated previously. Anderlecht give a another name that's more a alt name that the official name. As other exemple https://www.openstreetmap.org/node/6004362338 we keep the name of urban brussels although City of Brussels used a different name. 

So we need to have the same rules for case of theres different name ; we take one or other (urban or municipality) BUT we can not randomly decide witch is better and changing this in v1 , v2, v3 

My proposal is to take the urban brussels name as main name and the other name as alt_name
