Summary Not Providing Correct Totals

I have 4 accounts. The Accounts are fully reconciled but the amounts shown in the Cash Summary differ from those shown in the Bank and Cash Accounts Tab which are correct.In fact the Cash Summmary doesn’t list any totals for two of the accounts, lists an incorrect total for one of the accounts,and doesn’t even list the fourth account at all. I tried to add an adjustment just to see what would happen but that didn’t help. When I click the link for an account in the Summary, it only lists a few of the transactions. Where does the Cash Summary get its totals? Please help. Thank you.

Bank and cash accounts tab will show totals for all transactions entered into the system.

Cash summary is a report which is for specific period and closing balances are for specific date.

Isn’t this already mentioned in this recent post?
