Problem filling out the Hubspot form

I created a form in Hubspot.
Integrated Hubspot into Webflow via an application connector.

The Hubspot form works great on the desktop in Opera and on mobile in Safari.
But on the desktop Chrome and Safari, the form can only be filled out after clicking the Submit button.

That is, the logic on the Chrome and Safari desktop is as follows:

  1. press the Submit button
  2. fill out the form
  3. click on the Submit button again to submit the form.

I would like the form to be filled out immediately, without having to press a Submit button first.
