Contact form submission redirects to ID but doesnt submit

I have created a contact form using this plugin. When i click the submit button, it doesnt submit the form. It just redirects to the same page with the form Id e.g. /contact-us/#contact-form-1234

I checked the html form and this is the URL that is used in the forms action tag. Why is this not submitting to the correct URL? I have checked the console and I don’t see any javascript errors. Before or after the form submits.
