Hi @jvpdigital
The fields that are registered via PHP won’t show up on the backend (admin page). That’s because ACF doesn’t know where the code is located (you can put the code anywhere as long as you included the file). Even if ACF know where it’s, modifying the PHP code is not a good thing to do.
Also, creating the same field group on the backend will mostly cause issues in the future.
I suggest you export the field group to JSON or XML export file before generating the PHP code. That way you can import it back and modify the field groups from the admin page.
I hope this makes sense 🙂
