Bottom line: If you updated Quicken in March with 39.11 and/or 39.21, your paycheck information on transaction already entered can be corrupted. In order to fix, need to install 39.23 and restore a backup from before you updated (39.11 was released on 3/4). And yes, you manually have to do everything to bring up to date again.
