[AccessD] Conditional formatting -- known bug?

I've never used 2003's Conditional formatting in a report. I just tried to
apply conditional coloring to a grouped report. The conditions work just the
opposite of what I expect. 

For instance, if I want the value to be in red if it's less than 20, I tried


Less than 20 and less than or equal to 20 -- tried them both. Access is
displaying values greater than 20 in red, not less than.
