Hello,

Most likely you hid the section with the slider in the Elementor so you should edit this section and in the “Advanced” settings of the section turn off the “Hide On Mobile” option that is in the “Responsive” tab.

Otherwise, please provide your admin access to the private area, I will do my best to nail the issue.

Kind Regards
