google map

For the following adress: Schloßstr. 20, 51429 Bergisch Gladbach, ‘Germany I put Latitude 50.968698 and Longitude 7.156144 into Highend maps settings. With this data last week the correct Map in Bensberg was displayed. Today the same data display a map in Paris. I checked data with you LatLong link in highend theme and now I get the following data Lat. 50.965990 and Long 7.158440. So I changed this data in maps settings but again Paris is displayed in the map. Is this a google error or has it to do with the theme?
