404 error for missing wpmi.css.map file

In the browser’s Developer tools, I see a 404 error for the missing .map file, “wpmi.css.map”. Can this be corrected? It’s calling on the path to ../wp-content/plugins/wp-menu-icons/assets/css/wpmi.css.map Perhaps the call to the .map file can be eliminated during the build process? thank you. ??
