4-medium-small-1-ad moves the spoc around in the 4 column layout. In cols 1, 2, and 3 it's in position 1 in the second index. In the 4 column layout, it's position 3 in the 4th index. It should be position: 1 in the 4th index. This is likely not a visible issue, but a data one. Luckily this is low in the scroll order and likely not even an ad placement half the time.

I see this in both the hard coded layout, and the RS layout. I don't know about the merino layout, but that's also likely an issue.
