Thank you for taking prompt action and addressing this issue. The ads are now displaying correctly in a 2x4 grid. I was able to successfully change the grid to 3x3 and 3x4 but if I tried 2x5 or 3x5, the grid is displaying 6 ads wide, with a collapsed gutter on the last ad in the row.
2x6 and 3x6 grid renders correctly, so the issue is only with 5 ads across.
