Reconciling the bank account but cannot acces discrepancies

I have only recently started using the software and have tried to do a first reconciliation. I have followed the Reconciling bank accounts Guide and have a discrepancy showing in the report but the amount field is not a link. Is there something that I perhaps have missed in set up? I am only using a simple journal entry and reporting approach.

You can’t use Journal entries with Cash Accounts - read below
Have you activated Cash Accounts tab and created “New Cash Accounts”
