When I run an Account Balance Report for today only, it is correct. But when I run it for the last 12 months, with weekly intervals, one investment account shows a different current balance. It is based on the cost basis for the only security in the account, a US Treasury Bond which was purchased in the last 12 months. When I use a shorter period, the current balance changes, probably to what the value was at the BEGINNING of the period used.
What's wrong
