Change the URL to small letters

[Noshe07]

Please make the name of cities of lieferservice pages to small letters . Because I have indexed with small letters and now it is creating problems . So please change the url of lieferservice pages to small letters . I have also attached the file . Please see and make changes in name of cities by making letters small . Like if Lieferservice Krefeld is the page , than URL should be (lieferservice/krefeld) means k with small letters. And change for all cities.
If you have any questions let me know . Thanks
