Bestsellers Block in 4.0.3

I have added a top 5 bestsellers block to category pages. In version 4.0.2 it worked great because the products it grabbed were from each respective category where the block displayed. i.e. boat racing category displayed the top 5 bestsellers in that category.

Now in 4.0.3 it just displays the same 5 products. Not so good, in fact worthless to me.

Any idea on how to remedy this?

Weird, but his has somehow fixed itself overinight
