Justified won’t keep it’s line height

TLDR: My front end and back end don’t match. My theme is the likely problem, but I can’t find the correct class to override the CSS causing this issue.

So I am loving playing with Galleryberg. But I now have an issue where my backend shows the perfect Justified gallery I want, and my front end doesn’t show my chosen line height and makes an absolute mess out of it. (only the first 4 years of my problem page have Galleryberg, I found out I had an issue before I did all)

Online I found these to force line height, but it doesn’t work, and I think the class might just be wrong, but I don’t know. I’ve been trying to find it with my F12 browser option. But I can’t get it to work.

Theme: GeneratePress, Plugin: Galleryberg,

/* Force line height */
.gb-gallery-justified img,
.galleryberg img {
  height: 220px !important;
  object-fit: cover;
}

/* Keep container clean */
.gb-gallery-justified,
.galleryberg {
  display: flex;
  flex-wrap: wrap;
}
