Showing image captions on mobile version

Site URL: https://www.houseofbliss.com/portals-gallery

I'm using the "Avenue" template. On my page https://www.houseofbliss.com/portals-gallery, I have captions for each image in the grid. On the desktop, when I click on an image it opens a lightbox and the image captions are displayed. But on my phone, in the lightbox it shows each enlarged image, but where the captions should be there's a little white dot I have to click on to activate the caption. I didn't notice the dot for a while and I don't think a lot of other people would either. Is there a setting I can change to force the captions to always display in the mobile version?
