Please help me if you can.
After changing the picture in one of four circles on the homepage in 002060 template the circle changed to ellipse on its own.

I couldn't find where to change it back... Also the circles with the word "more" changed to ellipses on their own (but I don't mind those).

Please help me to either change it back to circle or to make them all ellipses.

The website in question is http://www.villa-mandalena.com and there you can see the ellipse standing out next to the circles.

Thank you very much.
