I'm building an app where I'm splitting a form between multiple screens. Previously, when using a classic form control, I would copy one form from one screen to another remove the fields and add the ones I want to include for that screen. For the app I'm building now I'm using a modern form control, which allows me to copy the form to another screen but when I add the new fields it's adding them in the classic form style and not the new modern for style. Is there something I'm doing wrong or is it a bug?
