Thumbnails in wrong place in Elementor, not showing up at all on live page

Seem to be having a pretty big issue here.

We have a product with multiple images, running latest Elementor, WP & Woo.

When using the Elementor product gallery widget the thumbnails show up on top of the main image (no matter the setting applied) and don’t show up at all on the live page.

When using the shortcode, the same thing happens.

Hope you can help, really excited to get this one working.

PS: How do you enable an embedded YouTube video in the gallery? That’s what drew us to this plugin, but can’t seem to find a way to do that anywhere, despite it being a listed featured.

Thanks!
