How to edit the Form Submission Message

Hello,

Does anyone know how to change and edit this message after a form has been submitted? I am able to change the bottom box but not the Header / Topic?

Any help would be appreciated!!

On the form, go to settings and choose SUCCESS
You can also change the Error messages
