Gallery (slideshow simple) captions on mobile are being cut off. Overflow not working correctly, help!

Captions in my Slideshow Gallery are getting cut/cropped off (Mobile_no code.png). I've tried allowing the overflow to be visible with the code below, but that extends the text below other elements under the gallery (Mobile_with code.png).

Code I used for caption:

.gallery-caption .gallery-caption-wrapper {
      overflow: visible;
    }

How can I make the caption fully visible on all screen sizes, and allow the content below the gallery/caption to flow properly after it instead of overlap?

I also don't like that the thumbnail list under the gallery disappears on mobile. Is there a way to keep that from disappearing?
