I can help you remove the duplicate entries, Charlie.
You can undo the bank transactions and leave the deposits in there to remove the duplicates.
The transactions will return to the For Review tab where you can match the deposits again. Doing this will not result to duplicate bank transactions and will not affect reconciliations.
For more details about excluding duplicate entries, you can check out this article: Exclude Duplicates or Personal Expenses from Downloaded Bank Transactions.
