Woocommerce checkout sections still isn't fixed

Ive followed the steps of uploading the update to my server through ftp and ive used the css code .woocommerce .col2-set, .woocommerce-page .col2-set {
width: 100%;
display: table-column;
} to try to fix it but the code only makes the entire table disappear.

Example of how the checkout page looks

Have a coupon…..
