Oh yes, this is quite problematic. Kirchberg on the one hand is a hill on which a church is located so it is a tag in the logic of museum-digital (there are many hills with churches) and on the other hand it is the name of many localities. I just gave all localities a homonym and sorted out Kirchberg (tag) and the respective Kirchberg at ... (placename with homonym). I had luck that it was always clear, which Kirchberg locality was ment. Thank you very much for the hint. It is fixed now.
