So this has happened at least 3 times in the last few months.
Quicken Deluxe for Windows
Version R52.20
Build 27.1.52.20
I used the calendar view to create a reminder and it's set for payment to various credit card companies (ie: Barclay AAdvantage card). I set it for the "current statement balance".
Due to some returns/credits, I had a month where instead of having to pay, I have a credit balance.
Quicken has decided to change the reminder in the calendar view to an INCOME reminder, and I have no way to edit/change it back via the Calendar view. Only solution I've had is to delete it and manually re-create it again.
This has happened to my Chase card(s) and Barclays cards, and Citibank cards, so far.
