There are 11 Cash Accounts as per the first screenshot but only 10 are being listed under Reports - Bank Reconciliation as per the second screenshot. Acct #11 is missing. Initially there were two #01 Accts, but the second entry was deleted. Have closed down and re-started Manger in case this re-aligned things.
Also the Bank Reconciliation list is not in sorted order
It appears that you need to click on the second screenshot to get full view - odd
