I know that it's important to reconcile your accounts. I'm here to help you.
When you go to the Accounting menu, then Reconcile, make sure to enter the correct data such as the Ending balance and Ending date. These are the basis to what are the default transactions shown on the Reconcile page. If you entered incorrect info, you can change it b clicking the Edit info button.
Also, you can still filter or sort the transactions. Simply click the Funnel icon and change the filter, then click Apply.
In addition, make sure to select All instead of just Payments or Deposits so you'll see all the transactions that you need to reconcile. Please check this screenshot:
