Plugin “breaks” the WooCommerce gallery images

I’ve added the plugin in and it ‘breaks’ the WooCommerce product gallery. Normally, the thumbnails below the large image are scrollable. When I activate the Light Box plugin, they all ‘clump’ in multiple rows.

Any way to solve this?

The button saying “Demo Video” on the right side is what we are using the Light Box for.
