Google Maps Position not correctly display in evolve theme

Hi,

i am using the evolve 3.5 contact settings and have created a contact page. The problem is that google does not know the proper address i am looking for, so i have entered latitude and longitute as address, which works perfectly fine when i copy an paste the position in google maps directly. But in the embeded map i am always of by a view 10 meters of the actual position. So it seems the information are not properly displayed in the map.

I have inserted: 51.98344, 12.9526
But point is displayed at: 51.98399, 12.94866

Any idea why the position is not the correct one? Looks like the position is converted into a google maps address and then displayed?

Thanks for any help. I would like to avoid using another plugin for displaying the map.

Thanks in advance.
