Can I delete an .ofx file that I imported to a bank reconciliation in Sage 50?

I thought I would try importing an .ofx file from my bank to reconcile our business checking account. I do not like how it turned out. Is there any way to undo or delete? Every time I go back into reconcile the account the import file populates in. I can't find anywhere in the forum or help that gives my an answer to my challenge. Does any one know how I fix this? Thanks in advance.
