Someone posted this problem back in 2023. The problem wasn't resolved and the topic was closed.
While there was a suggested workaround from UKR to pre-schedule the payments, it didn't seem to help. I already do that with several credit card payments and other scheduled transfers and the result is typically double registry entries. There's an uncleared pre-scheduled entry and the cleared downloaded transaction with the category set as a transfer back to the same account.
It's a real problem and it has been going on for several months. It started around the time I had to do a file repair using the export import method which required reestablishing all the online bank credentials so I always assumed this was just something I needed to live with until I saw others were having the same problem last year in the closed thread.
At the time I also noticed Quicken wasn't as good at finding matching transactions as it has been. It may be a related problem.
My initial theory is it may have something to do with memorized transactions so I'm going to try to delete some of the suspicious memorized transactions with transfers as the category. I'll see if that helps.
If someone else is aware of a fix, let me know.
