Incorrect total results in performance report graph

Rick B

In performance reports graphs the results are correct by time and account slices but when using investment types for subtotals the individual classes are correct but the totals are not . I have attached a screen capture to help better explain . I have not assigned any investments to option groups. The total for the individual class and the total line should match . Of course not an issue without subtotals but with I have no way of seeing or comparing classes to the overall total .
