V14 - Custom Field different from Customize Form for specific doctype

I modified Item doctype using Customize Form like I always do. Move some inputs and added some other. On v11, every change that was in Customize Form, reflected aldo on Custom Field. I always make the changes on dev environment. execute either export-fixtures or export_customizations.

On v14 it does not work like this. Is it a bug, or the logic has changed?

Thank you in advance.
