Please try to find with the key ‘#sns_custommenu ul.mainnav li.level0 > a’, which container the code like below

font-weight: bold;
  display: block;
  padding: 0 22px;
  position: relative;

then change 22px to 15px or another one that you see properly.
However you should not add too much the item into Main menu.

Thanks you,
