Try to add the following code

.blog-design-masonry .entry-header {
    border: 1px solid #000;
    padding: 20px;
    border-bottom: 0;
}
.blog-design-masonry .entry-content {
    border: 1px solid #000;
    padding: 20px;
    border-top: 0;
}

And please remove yours

.blog-design-masonry {
    margin-bottom: 50px;
    text-align: center;
    border: 1px solid !important;
    padding: 2% !important;
}
