Best Sellers will not show on center column

Hello,
No matter what I try I cannot get Best Sellers to show on my home page, center column. I can set it to show in the left or right side boxes and it shows every time as it should. And yes, I have "sold" products via testing and they do show up if the module is placed in a side box.

I've turn ON for single column, tried it with left/Right on and off and even changed the sort order number from 0-3 (I only have 3 items set to ON for the center column.)

I do not see an option for Best Sellers under Configuration > Index Listing.

Any ideas?

Thanks!
