Trying to disable all notifications except for one on woocommerce checkout page with css [closed]

Even though the css selector I used doesn’t match the HTML structure, this worked for only allowing one notification through when more than one field is not filled out on the checkout page of a woocommerce site:

#Content > div > div > div > div.section.mcb-section > div > div > div > div > div > div > form.checkout.woocommerce-checkout > div.woocommerce-NoticeGroup.woocommerce-NoticeGroup-checkout:nth-child(1) > div:nth-child(n+2) {
  display: none;
}

Not sure why > div:nth-child(n+2), all I should need is the first nth-child to be nth-child(n+1)
