Extra column in BW query data?

I'm getting an extra blank column in my BW query data that does not show in data preview mode. I'm expecting data, based on the preview to look like this:

CCtr Yr Amt Qty

375 2010 10 10

But getting instead:

CCtr Yr Blank Amt Qty

375 2010 10 10

I'm sure there is probably a workaround for this, but it seems like a bug. Anyone else experiencing this with the "direct" connection to BW query?

I'm on Xcelsius 5.3.4.0, Build 12,3,4,1038. BW 7.01 SP6.

Thanks,
