Images not showing in Elementor

Hi,

I have downloaded the GT3 Elementor Photo Gallery to use with my website however this feature is not working. You can drag the widget onto the page and then begin setting up your gallery however when you select a Gallery that you have already created it will not show the images in Elementor or on the site once you save changes. Please can you help. All plugins and Elementor are fully up to date and currently running Ocean WP Them on WordPress.

Thanks
Ian
