Bootstrap 5 - mt-5 overrides mt-md-0 on ≥768px screen size

on medium and below medium screen sizes i have 4 cols that will be above each others, i need to give 2 cols some margin on medium and below medium screen sizes and remove it on above medium screen sizes, so i give it class mt-5 mt-md-0, but the mt-5 class overrides mt-md-0 on above medium screen sizes, am i using it the wrong way ?

import React from "react";
import { useTranslation } from "react-i18next";

function CoreValues() {
  const { t } = useTranslation();

  return (
    <div className="container-fluid px-0">
      <div className="row px-lg-5">
        <div className="col-lg-6">
          ...
        </div>

        <div className="col-lg-6 mt-5 mt-md-0">
          ...
        </div>
      </div>
      <div className="row mt-5 px-lg-5">
        <div className="col-lg-6">
          ...
        </div>
        <div className="col-lg-6 mt-5 mt-md-0">
          ...
        </div>
      </div>
    </div>
  );
}

export default CoreValues;

Johnny — I've created an html code snippet based on your question. If you run and expand the snippet, you can see the margin-top switching from 3rem to 0 on larger (> 768px) screens.

The attached screen capture shows mt-md-0 overriding mt-5 in developer tools.

If you are experiencing something different, it would be easiest to see what's happening if you would post a functional code snippet, rather than copying your code from your React module.
