Footer area widgets not displaying correctly in Askbug Theme

Hello,

I am using widget for the footer area (the provided by Askbug):

1) They do not display in line, and there is a gap in the right hand side.

2) If I want just to display 3 widgets, it is not possible because it shows the code by defect. (I have try to delete the code in the footer.php but I did not make it work)

3) Footer widgets does display in mobile devises
