Need help with sub form fields

Need some UI and UX suggestions and help regarding the following sub-form section Subform Screenshot

Is this ok? I want to clarify to users that by clicking on "Add Extra Data" it will add Title and Extra Data text boxes. Also, Users can remove those by clicking "Remove". Is this UI/UX clear enough?

Are there better techniques to handle this kind of situation in forms?

Thank you in advance for helping.
