Cannot categorize a bank deposit to an income sub-account

Cannot categorize a bank deposit to an income sub-account

When I go to categorize a bank deposit, I am not able to see any income sub-accounts.  If I set up an income account without a parent, then I am able to categorize a transaction into that account, but as soon as I make it a child account, it disappears from the transaction categorization options.

I don't want to use "other income" because then it appears an non-operating income in the P&L report.
