I Need help in Bank reconciliation .

I have done the below steps :

1.Created an invoice .

2. Registered payment to the bank.

3. Created a bank statement that once i want to reconcile this error is generated :
-Getting Error "Entries are not from the same account: 100201 Bank Suspense Account != 100204 Bank"

-Status always shows "processing" for the bank statement .

- Status always shows "IN payment" for the invoice .

-How to get Bank statement  validated and invoice status paid ?????

-I cannot find any Reconcile button in Accounting Dashboard.
