Why can't dividend income in a Roth investing account have the correct category of Investments:Dividend Income Tax-Free? It automatically picks Investments: Dividend Income as if it's taxable, which is wrong. This is not autofill either. It's pre-picked and cannot be overwritten. The correct category is indeed available. Seems like a bug.
I'm finding that the only option is to use Payment/Deposit and set a QuickFill rule for a custom Payee, then write a memo for the ticker symbol.
It defeats the purpose of having a retirement account.
