Balance Sheet report is displaying wrong balance for two accounts

Hello experts

We are facing an issue due to which Balance Sheet report is showing wrong balance for a couple accounts, if we compare to the balance that these two accounts have when we check by looking on them on the chart of accounts. So, the amounts that are being displayed on the chart of accounts are the correct ones, and the results shown in the Sheet Balance report are incorrect.

The thing is that these accounts are the two accounts involved in the Period-End Closing process, as they are the "Exercise Results" account and the "Unallocated Items" account. Therefore we think that this is a closing process related issue somehow.

Is there anything that we can do in order to solve it? Or is it better that we open a SAP Note?

Thanks in advance and regards
