Avada not working with plugin

I have been trying to embed a video in my WP site with Avada theme.

I have used the standard builder (Avada fusion builder/wireframe), and the default WP editor.

I can embed a code, but it doesn’t show up on the live page.

Sometimes it shows the text, “Enter your content here,” even after I delete that text.

Is there anything specific I need to check in Avada?

Thank you
