Map widget not displaying at the bottom rows/parts of the website

Hi, I have a strange problem and I could not figure out what is causing it. I want to display a map from this plugins widget Google Maps Easy. Everything works fine when I put the widget in a row in the upper part of the web page – http://360.nikolay100.com/map/. But what I want is this map to be displayed in the lower part of a page. When I put a couple of rows with text and then put a row at the bottom with the Google Maps Easy widget it hides somewhere – http://360.nikolay100.com/. Actually when I start moving the Map widget down it shrinks every single row.
It is clear that the problem is not with the Google Maps Easy plugin, because it works in the first example. And it is not the theme, because this happens with every theme I have tried – around 20 of them.
Please help.
