@VLD549: Had you inspected the history of the object prior to writing your comment, you might have noticed that the Dutch spelling in two words was introduced in version #11 of the object several years ago, and by another mapper, here: https://www.openstreetmap.org/changeset/50993775

What I see here is that luschi only applied a minor fix about the "*" sign at the end but this is unrelated to the choice of writing it in one or two words.
