Lightbox navigational arrows not clickable

Navigation arrows in the image lightbox are greyed out and appear to be behind the background overlay. I note you also have the same problem on your own website page examples ( portfolio-for-elementor website example ).

If it wasn’t for this, I’d give this plugin top marks, because it looks fantastic. …But if it doesn’t work it doesn’t work. Would love to know how to fix this please? Any ideas?

Thanks

David
