Shortcode not working with Avada theme

Hi

I’m trying to use the shortcode [booking-form] with Avada theme.

When I use it in an empty page, it displays the form.
When I use it in a page that contains already some other code, the form does not show up.
In my case, I insert the [booking-form] inside a text shortcode of Avada.

When I check the generated code, I see this (below) :

Any idea ?

Thanks very much for your help
