Following a recent Quicken update I noticed that the graph on the Reminders windows (All bills and reminders tab) was showing a huge jump in my balance (i.e. hundreds of thousands of dollars) occurring on an upcoming date. When I hovered on that date in the calendar I was presented with many duplicates of one of my income reminders for that date. By many, I mean too many to display on the screen. The list went from top of screen to bottom. I decided to delete the income reminder, but then I saw a similar issue with a scheduled payment being repeated many times on the same date and thus showing a huge negative balance. I decided to delete that one too. I then did a backup and recreated the two entries and all looked OK. I then decided to do a validate. Validate reported one error with my reminders. When I opened the reminders I found there are now well over a hundred identical "zero" entries. See screen shot. Each of these shows an "only once" payment of zero with no due date and status "done." Also no payee. How can I get rid of these all at once? Deleting them one at a time is super slow. None were there until I did a validate. I also tried a Super Validate that didn't find any errors.
The issue seems similar to a recent closed thread at
