each month a transaction from Schwab for a Schwab managed account on or about the 15th of the month comes in with a zero in the amount field. this transaction is the monthly bank interest for the account.
I wonder if the "Schwab managed account" aspect has anything to do with that, though I wouldn't think it would.
I've occupationally received interest from Schwab Bank in a non-managed account and those events always show up properly.
If you have other downloading Schwab Accounts in your file, do those Accounts properly record that entry?
