Automatic entry of memorized transactions

I have memorized transactions that still come up for entry even though they've been deleted or their names have been edited. How do I go about cleaning up these items so that they do not come up again on the automatic entry list that appears when logging in?  These items only appear when I open QBs initially and I am not able to find them in the list to edit them.  It appears that the items in question in the system or renamed as memorized transactions. Help!
