I am having this same issue with 2 memorized transactions.  I had one memorized transaction selected for Auto entry.  Then I deleted and when that didn't work created a fake transaction, was notified it was a duplicate transaction and did I want to replace it.  I selected yes hoping that would give me something to work with.  Now I have 2 transactions that pop up as a reminder every time I log on and I can't get rid of them.
