Management Reporter 2012 and AX 2012 Beginning Balance Error

In AX my client uses the Accounting Year Close procedure to close the previous year (2012).

Anyway it is necessary to reopen it, adjust the balances, and do the accounting year close again.

Thus on the GL transaction for each BS account we have transactions like these all at 01/01/2013:

Opening +1000 (original closing)

Opening -1000 (reversal of original closing)

Opening +1100 (closing #2)

In AX the beginning balances are OK, but the management reporter doesn't "see" the reversal, and he returns as the beginning balance 2100 (sum of 1st and 3rd line).

Does this happen to everybody, or did I setup anything wrong?

In column definition I tried with YTD/BB and PERIODIC/BB I have the same result..

Thanks for help
