Quicken Classic Premier Mac Version 7.3.2 (Build 703.50456.100) under macOS 13.5.2.
In an investment account, I want to change the transaction category for reconciled transaction from "Interest Earned" to "Investments:Interest Income", both of which are pre-defined categories. When I type "Investments:Interest Income" into the category, it asks if I want to "Create a new Category 'Investments:Interest Income'". I clicked on this to create a new category even though it already exists. When I click on "Save", the category reverts to "Interest Earned". How may I change the transaction category for reconciled transaction from "Interest Earned" to "Investments:Interest Income"?
