This option allows you to remove all unexplained transactions on an imported statement. To do this you will need to specify a date range - all unexplained transactions that have payment dates outside of this specified range will be removed.
Navigate to Money > Bank accounts.
Click on the Explain link beside the imported bank account that you would like to narrow the results of.
Click on the [Bulk delete unexplained transactions] link at the top of the statement.
Select a minimum and maximum date - any unexplained transactions outside of this date range will be deleted.
No explained transactions are removed.
