Bank reconciliation not reconciling

I have entered all my transactions and paid them for the month.  I then go into bank feeds and match everything.  Then when I go to reconcile account and enter the bank statement figure it is out.  I untick everything and go through the bank statement and match every transaction individually in MYOB.  It still does not reconcile.  I have to untick everything. Then reconcile each day individually.  Entering the bank statement figure for each day.  When you entered the last day of the month it is correct and reconciles. I have tripled checked the months transactions to make sure nothing has been missed or entered twice to put the reconciliation out and the transactions are correct.  This keeps happening each month now.
