I have a pie chart report which labels the slices by age ranges, e.g. 10-19, 20-29 and so on. It works fine except for the first line of the legend where what should appear as '10-19' instead appears as Oct-19. I can think of ways to work around this but I'd like to know what the problem is. I can find no way of setting a format for the legend defining the label as text and not a date.
