I've searched but the closest problem I've seen addressed to this has been syncing with the cloud. I do not, never have synced with the cloud. Kinda the whole point of using Quicken.
I use two Income Reminders based on Memorized Payees to enter my paychecks; one mid-month, one end of month. I have been doing this, literally for decades. suddenly a month and a half ago, Quicken has started deleting the Categories and amounts from those two transactions after I run One Step Update. The transactions I have already entered are unchanged. The Memorized Payee split is unchanged. The Transfers within the transactions for some reason remain but all the Categories are deleted.
I edited both to reenter the categories. I tried deleting and recreating the transactions. I tried creating new transactions with a different Payee name. Locked or Unlocked. The "Remove memorized payees not used..." is unchecked. Validating and Super Validating the files does give any hints as to problems which would cause this. I have uninstalled/reinstalled Quicken R64.30 Build 27.164.30. I have restored multiple data files up to five months back. The splits are there when I restore the file but as soon as I run OSU, they disappear. Quicken support has been unhelpful. Have any suggestions?
