Captions not showing up on Full-screen slideshow gallery on Mobile

Hi Squarespacers – I need your assistance as I can't find an answer or solution to this. On the home page of the site I'm designing for a client, we have a full-screen gallery slideshow. On desktop, it looks fine and the captions display directly below – on Mobile they disappear. The captions have to appear on mobile for copyright reasons – can someone help?

I've tried targeting it with bits of CSS but I don't think I have right parameters.
