Windows 10.
Thank you for all the suggestions but I don't think the issue I'm having is related to a configuration issue. Looking back through my registers, particularly credit card transactions, the anomaly with the Payee name began in middle of August. I made no changes to Quicken settings to my knowledge. Prior to posting my request for help, I completely cleared all memorized payees and have never used Renaming Rules as I never had a need for this feature. From what I can deduce on my own, the download interface is what changed in middle of August, or a Quicken update may have caused the issue. I'll try some of the suggestions above regarding the use of Rename Rules as a workaround, but I shouldn't have to. Logically speaking, payee name should only contact the name of the Merchant as mapped by the sending bank. Merchant location and Phone Number should not be concatenated into the Payee field - which appears to be what is happening. Maybe the sending bank is at fault? Unfortunately, I can't troubleshoot that end of it. Thanks for trying to help.
BTW I will mention a couple more options:Edit -> Preferences -> Downloaded transactions -> Automatically create rules when I rename payeesEdit -> Preferences -> Downloaded transactions -> Let me review/confirm the automatically created rulesThose might make it easier to create the renaming rules instead of jumping in and adding your own.But I'm not so sure how good Quicken is about getting the right "keyword(s)" for the match to the downloaded payee, so be sure to turn on the confirmation.I personally like to create my own.The renaming rules tend to be a bit of a pain at first, but pretty quickly you build up the ones you deal with all the time, and it "just works".Consider yourself lucky. On the Mac side they don't have any renaming rules. Or should I say they don't have any they can directly edit. They basically do some kind of drag and drop of the a transaction with the right name on the downloaded one, and it creates it own hidden rules.Automatically creating renaming rules and memorized payees can be great for getting started, but no guessing like that is perfect and sooner or later you need direct control of it. And the Mac people don't have that.
