Border around Instagram block not working

I'm not sure why the right side only of the reel on the Instagram isn't working. 

This is the code I'm using: 

//Instagram grid in footer
.sqs-gallery-block-grid .slide .margin-wrapper a.image-slide-anchor[href] {
    border-radius: 27px; border: 4px solid #7D42FF;
}

.instagram-block .sqs-video-wrapper .sqs-video-overlay {
    border-radius: 20px; border: 4px solid #7D42FF;
}
