Management Reporter - missing date in header

I have a column layout that has about 24 columns across.  Pretty basic, it has the current month, current month-prior year, variance for different states (pulled from reporting tree).  In the column headers, @FiscalPeriod/@CalYear, @FiscalPeriod/@CalYear, "Variance".  For two-thirds of the columns, the headers appear as "8/2016", "8/2015", "Variance".  In the last set of 4 states, all that appears is "/", "/", "Variance".  I've tried putting in some other AutoText options in problem columns, but still nothing prints.  Any idea how I can resolve this?
