I checked our your site on a smaller screen size and I see what you mean.

Part of the issue is your menu titles are quite long, which is unusual.

Here is some CSS code which will align them to the opposite side,

@media (min-width: 768px) {
.navbar-right .dropdown-menu {
/* right: 0; */
left: auto;

Add this code in the Custom CSS field of the Custom Code section in the Integral Options Panel.
