I looked at one of my accounts and the ending balance is not tying out with what the investment growth is and there are no expenses in that year. Why isn't it tying out?
This is likely due to the setting 'Rebalance Investments Annually'. If this is set to Yes the program will rebalance all taxable accounts and retirement accounts except Roth IRAs and Inherited IRAs. They will be rebalanced to the same percent of the portfolio they were at the beginning of the period.
