HTML Form title - how to edit?! Hubspot embed

Hi - can anyone help me?

Our developer has set up a landing page and I’ve duplicated it. I’ve figured out how to replace the form so it directs to the correct form in hubspot and edited all the text however when you click on the button to download the guide the form looks very odd and has a title that needs changing and I can’t find.

The title of the pop-up is: Fill in the form below to download Document playbook

Huubspot tells me this is not part of the form therefore the HTML embed is correct, it’s something on webflow but I can’t figure out where it is or how to edit the text or stop the pop-up looking like there’s a form within a form.

I’m totally lost - can anyone help me?
