I've tried several times to install a 4-wide horizontal link unit on my "Fictional John Smith" web site and all I ever get is one link (with lots of white space) that says "John Smith", which causes me to remove it right away again.
Have you tried to block that particular advertiser? Then you might see other ads.
I've seen ad units that are really CPM ads, all four ads, or all two ads, are for the same company or URL. Try blocking these and see what happens.
My only other comment is, every time you play with the competitive ad filters you may go through a day or two or lower earnings. Some call this Smart Pricing, but frankly I'd call it a "change" penalty on top of Smart Pricing.
