As you can see, there’s “Meklar” (wrong) and “Mecklar” (correct, see Wikipedia) shown on the map. I’m not sure where the “Meklar” comes from, maybe it’s meant to be a train station? It is correct, that there’s an old train station in Mecklar but it is out of order. However, I’m not sure how to correct (or delete?) the “Meklar”…
What would be the right way to solve this problem?
You can safely change the ‘name’ tag value to ‘Necklar’. Perhaps adding a ‘note’ tag in which you state why you’ve changed the name but that isn’t necessary at all.
