Duplicate EFT Transaction

Hi

Please can I have some help, I am trying to reconcile my accounts however duplicate expenses have occured after creating rules after i imported a statement.

I have since deleted the import and cancelled the rules i created but the duplicates remain.

I have so many of them, how can i get rid of them as you can imagine my expenses are doubled on my dashboard. Or is it possible to go back to a few days ago, im working on MYOB Business,

Thanks
