Use your Gear (⚙️) icon, then go to Bank Accounts.
Confirm each account is only synced once.
If there's more than one connection for any of your accounts, click the toggle button under Show account to turn it OFF. This hides all entries.
Step 2 - Exclude transactions you don't need
Go to your Transactions menu.
Locate a record and hit it to expand its view.
Tick the Exclude this transaction checkbox.
Additionally, if you accidentally added a transaction that's already been downloaded from your bank, you can delete it. Once you've cleared up the invalid records, reports will display accurate amounts.
