Home Panels do not retain size

I have 3 panels for my main display. Since we upgraded to Groupwise 2014 (R2), the panels are reset to the default size whenever I view a different folder and then navigate back to my home folder. Since two of the folders only ever have 2-3 items listed, this results in a lot of wasted space, and I have to scroll in the top folder which does have more items.

Is this a bug, or is there something I can do to force GW to save my panel sizing?
