Center headers within a cell (After 8.2 release)

Hi team, my client was excited to upgrade to 8.2 to center headers. After turning on this functionality, what we have found is below. Can you tell me if I'm missing a setting here to make it work like we want it to?

Finding: It only works if it is the top row AND it is a single member repeating. Notice how the months aren't centered, also notice that even though the scenario is merged and in the center cell, it is not centered WITHIN the cell.
