When I run validation on the file, there are no inconsistencies, but there's a bunch of messages about missing splits of various stocks, for example
Quicken has found 1 stock split(s) for account "Schwab", security "Alphabet Inc. - Class C Capital Stock", on 8/31/2020 that might be missing.
But all transactions of this security are dated later that 8/21/2020: 9 shares were bought on 5/23/2023, got several dividends (not reinvested), and sold 9 shares on 7/15/2025. So I'm wondering what gives, and if I'm supposed to do anything to make the message go away.
