Hello,

1-This is because the product above has longer title, resulting in two lines. To fix this, just set the products to a minimum height. Add this code into your Custom css box:

.shop-products[data-grid-cols="4"] .product_item li.product, .product_item .inner-wrapper {
    min-height: 490px !important;
}

2-Add this code:

.cl-woocommerce-results-title .sort-options {
    padding-bottom: 90px;
}

Let us know.
Best regards!
