Elementor forms Multiple select not responsive on desktop on eleme

I created drop down lists using the type select on Elementor forms. I want users to select to be able to select multiple choices or items on the drop down lists so I enabled the Multiple selection button. When I check the form using my mobile phone it functions the way its supposed to but it doesn’t on the desktop. Attached is the link.
