7.0 - Gallery image crop issues

Site URL: https://www.miriamguttmann.com/still-life

Hi there, 

I have created a website with Brine, and I am having issues with the galleries. They are cropping the bottom of all of my images. Is there some code I can add in to stop this from happening? 

i.e. look at this page: https://www.miriamguttmann.com/still-life
Note the image with the yellow base - we should see the entire base + a little of the background. 

Try adding this to Design > Custom CSS

.sqs-gallery-design-stacked-slide img {
    width: auto !important;
    height: 100% !important;
    left: 50% !important;
    top: 0 !important;
    right: 0 !important;
    bottom: 0 !Important;
    transform: translateX(-50%);
}

Thank you!
