Websites are built for users not for committees who frankly don't have a clue about design or what their users want. If such a committee won't listen to sound advice that will improve things for users then I would walk away from the job.
You might want to take a look at the width that has been applied to this element <div class="grid-item W2 S-AMERICA AFRICA" style="position: absolute; left: 1080px; top: 811px;">
give it a width of 25% like all the others instead of the 50%.
That will fix your issue... which incidentally is CSS related.
