I have a brokerage account, MS, and a CC account AmEx. For years we've made electronic payments from the MS account to the CC account. It has worked correctly and both accounts were reconciled and balanced as of 2/28/23. When I went to balance on 3/31/23 both accounts' starting balances didn't match the prior month ending balance. I tracked it down to all the electronic payments in the AmEx account from 6/21 to 3/23 had been changed by Quicken. Instead of being from MS to AmEx they all showed from AmEx to AmEx and the corresponding payment entries in the MS account were gone. All electronic payments in both account before 6/21 are still correct. File validation didn't find or correct anything.
