Inserting shortcode causing problems and output css classes

[lisandi]

When I insert [dms] into your shortcode in menus than a lot of code gets outputted which should not happen.

class="home page-template-default page page-id-11 logged-in admin-bar no-customize-support airplane-mode-disabled airplane-mode-no-qm et_pb_button_helper_class et_fixed_nav et_show_nav et_secondary_nav_enabled et_secondary_nav_two_panels et_primary_nav_dropdown_animation_fade et_secondary_nav_dropdown_animation_fade et_header_style_split et_pb_footer_columns4 et_cover_background et_pb_gutter osx et_pb_gutters3 et_pb_pagebuilder_layout et_smooth_scroll et_no_sidebar et_divi_theme et-db et_minified_js et_minified_css">

When inserting only Text into the Shortcode fields than it works but only without shortcode!
