why would my cube show the wrong master data when it is correct in the MD

I have an odd situation. When I go to display company code, which I have set up as an attribute of cost center, it displays the wrong value. However when I go to cost coetner and look at the company code it is right there. We tried re-loading the master data and that didn't help. I don't wnat to reload the cube if possible. Also racn checks on the cube and master data an no errors occurred? Is there a way to see if the wrong SID is attached?

thanks
