Thank you for your response, but this does not resolve the issue.  Simply blocking reminders via Preferences, blocks ALL reminders, which is not the idea.  I had previously already changed the dates for the transactions in individual memorized transactions from the memorized transactions list.  This also does NOT remove prior date Reminders.

I have resolved the issue, but the only manner in which it appears that this can be done is by deleting the existing/current (generating prior date reminders)  and then recreating the Memorized Transaction.

This is not an ideal option, but it does create the desired outcome. 

Poor software design.  The change of date suggested should work, but it does not.
