The mosaic plot and legend generated by PROC FREQ might incorrectly contain gray areas instead of being colored by the standardized residuals.

This problem is most likely to occur when the TABLE statement in PROC FREQ  includes the  PLOTS=MOSAICPLOT(COLORSTAT=) option with a value of STDRES or PEARSONRESID and the data set contains missing values.

There is currently no circumvention for this problem.
