Instagram Carousel Feed - Video bug?

Site URL: https://thewildones.squarespace.com/?password=pearler

I've checked my codes a few times, and I just can't seem to figure out why the Instagram videos aren't appearing square like the rest of the feed. Any ideas? Thanks!

Don't remove your code

Try this CSS

div.instagram-block .sqs-video-overlay img {
    border-radius: 1.875rem !important;
    width: 100% !important;
    left: 0 !important;
    margin-left: 0 !important;
    margin-right: 0 !important;
}
