Row suppression not working with dynamic cube?

Hi folks,

My suppression in my cubeview doesn't work. If I turn on any suppression (including 'invalid') the cubeview returns blank (no rows at all). It's a cube that's been loaded with dynamic data services and the data is showing as NotStored. I wonder if that could be the cause? Anyone else observe this or have any tricks? I've tried every combo of suppression option I can think of... I'm surprised it would return nothing even with only 'suppress invalid' checked..
