Error updating Journal Entry doctype: fieldname conflicting with controller

Trying to update the Journal Entry doctype. Doesnt matter what field I change, when I hit save I get an error message: Fieldname {Name} conflicting with a controller method of the name {name} in Journal Entry.
Fresh install v13.3.

Any suggestions?

I’d need more info to help you troubleshoot properly, but generally speaking it’s not a great idea to edit core doctypes directly. If you rename a field expected by a controller method, you’ll end up crashing (and I suspect that’s what’s happening here).

Can you clarify what you’re trying to do?

Are you trying to change the DocType itself? This is level is not for beginners.
