Images not scaling properly between desktop & mobile screen sizes

Is anyone able to help me figure out why some of the checkmark images are scaling differently than others? This is happening across our site (enticedge.com), on almost every page. Our team can't figure out why some checkmarks or X's are enlarging when the screen gets smaller and others are shrinking (they're all set to fit not fill, and are all the exact same size). The spacing between elements also seems to be scaling incorrectly -- adding space between text blocks that wasn't there when we hit save (for example after the first section on the left). When we go into our account, we're able to fix all of the spacing and scaling issues, hit save/publish, but then a few days later all of the spacing and scaling will be out of whack again 🤪 It's been driving us crazy! Would love any help or advice!

Can you share link to this page? I don't see it on home page

Try this CSS code (Website Tools > Custom CSS) to set fixed size for all tick images

.fe-651ee5b5ac1f6b435888cfbb img {
    width: 30px !important;
    height: 30px !important;
}
