خطا در کمپایل مقدار media با استفاده از mixin و متغییر در scss

سلام

من یک پروژه آماده دانلود کردم وقتی در vscode با استفاده از Live sccs Compile فایل ها رو تبدیل میکنم در بخشی از فایلها برای media مقادیری با استفاده از متغییر های تعریف شده و mixin به فایلهای css اضافه میشه که به نظر من اشتباه هست و تا به حال من همچین دستوری ندیدم یعنی به عنوان نام کلاس قرار میده. لطفاً راهنمایی کنید اشکالش کجاست؟

بخشی از خروجی:

.d-f {

  display: -webkit-box;

  display: -ms-flexbox;

  display: flex;

}



.d-if {

  display: -webkit-inline-box;

  display: -ms-inline-flexbox;

  display: inline-flex;

}



@media screen and (min-width: 1440px) {  .d-f\@xl\+ {

    display: -webkit-box;

    display: -ms-flexbox;

    display: flex;

  }

  .d-if\@xl\+ {

    display: -webkit-inline-box;

    display: -ms-inline-flexbox;

    display: inline-flex;

  }

}

متغییر ها:
