Gramps 5.2.4 (finnish translation) and Windows 11:
I try to delete one unused transaction type. Copilot AI gave advice " Navigate to the Transaction Types: Go to the menu and select Edit > Preferences > Transaction Types.
I can’t see “Transaction Types” in Preferences. How to resolve?
I’ll assume that it is a custom type that you no longer use or need.
Use the Type Cleanup addon tool. It finds any of your custom types wherever found, Events, Attributes, etc, and allows you to edit them or to delete types that are no longer used.
