The official name of this stop is "Alma".
This is the correct spelling, and this is how it should be written on OSM.

You changed the name of the stop and changed it into "STIB / MVIB - Alma", which is a strange mix of the operator and the stop.

This is incorrect because we start having validation issues and strange value in apps.

Perhaps you thought that it would be helpful, but it isn’t.  If you decide to rename Belgium on OSM into "Belgium,  a small country in Europe", you may also believe it is "helpful" that we get this information directly in the name, instead it will be seen as vandalism.

The entire public transport infrastructure is already mapped.  It is okay to bring some details like waste baskets or cameras if you want, but please do not change the names of stations, lines or platforms.
