Cloning form and then change the name of the form

When you clone a form and then change the name of the form, it leaves the name of the original form in the html 'title', and we can find no way to change it. It should change the title to match the name of the new form. 

Are you referring to the browser tab title? If yes, then please try updating the Page Title in the Form Settings. Here's how: How-to-Change-the-Page-Title-of-the-Form.

Let us know if you have any questions. Thank you.
