Reconciled Transactions have been Recategorized

Rad

my reconciled transaction history has been modified by "bill and income reminder" category changes. Why is this happening? How do I restore years of history?

UKR

While making category changes, did you get a prompt asking about updating past transactions? If so, what did you reply?

There's a new option setting in Edit / Preferences / Data Entry & Quickfill which was recently added to Quicken:

Could this be what's been biting you?

If you can't reverse the unwanted past transactions' changes using Edit / Find/Replace or Tools / Recategorize the only way to undo those changes would be to restore your Quicken data file from a Manual or Automatic Backup taken prior to the problem first occurring, if necessary going back to older backups until you find a file that does not exhibit these symptoms.

My Date entry and QuickFill boxes are checked as in your example?. NO I was not prompted about updating past transactions? All of these transactions are recurring split transactions and the changes that were made eliminated three of the four line split and posted the entire total to one category. I can't use the edit/replace tools to rectify. This is a VERY disturbing software bug that must be impacting other users.

This is much worse that originally thought. ALL split category transactions have been reduced to one category with the entire transaction posted to just one category. HELP!

Sorry. Looks to me like Mr. Murphy has taken a pitch fork to your data file and stirred it up like a compost pile.

I recommend you restore a backup of your data file, as I said earlier. Find an older version that is not messed up and bring it forward to today.

If/when I'm able to restore the PC data the Mobile app should be avoided. Until there is admission from Quicken Support that this is a very serious bug and they have a plan to FIX it, I will have to rely on PC data entry exclusively for financial transactions or find a more reliable mobile finance tool..
