Avia Layout Builder av_contact

Hi. We’re using the Enfold theme.

I have taken over development of the site.

On our contact page, we have the following code in our Avia Layout Builder:

[av_contact email=' (Email address hidden if logged out) ' title='Send us mail' button='Submit' on_send='text' sent='Your message has been sent!' link='' subject='' autorespond='' captcha='']
[av_contact_field label='Name' type='text' check='is_empty']
[av_contact_field label='E-Mail' type='text' check='is_email']
[av_contact_field label='Subject' type='text' check='is_empty']
[av_contact_field label='Message' type='textarea' check='is_empty']
[/av_contact]

However, this only produces a Submit button, with no form fields.

How can we fix this?

Thanks.
