module class suffix not working

hi

im trying out a new template with css4. my problem is that the module class suffix i add on the cart module doesn't appear when inspected . My cart module is suppose to appear only on mobile or xs. im using d-block d-sm-none visible-xs as classes. i added css3 library just to make sure since my template is css4 capable. But the class suffix is still not appearing when inspected

i also tried to use an ordinary custom template to check if the issue is the template but it works. i added a module that says "test should dissapear on sm". on the photo it disappears on larger screens because the classes are taken into account. i guess no problem with the template.

how can i make hikashop recognize the class suffix? or how to fix?

i send a photo.

please help

thanks

great its working

thanks
