Menu

Hi, I have question about menu. I get this message on the webisite:

*{"container_class":"u-menu u-menu-dropdown u-offcanvas u-menu-1","menu_class":"u-nav u-unstyled","item_class":"u-nav-item","link_class":"u-button-style u-nav-link","link_style":"","submenu_class":"u-h-spacing-20 u-nav u-unstyled u-v-spacing-10 u-block-cf63-14","submenu_item_class":"u-nav-item","submenu_link_class":"u-button-style u-nav-link u-white","submenu_link_style":"","r_menu_class":"u-align-center u-nav u-popupmenu-items u-unstyled u-nav-2","r_item_class":"u-nav-item","r_link_class":"u-button-style u-nav-link","r_link_style":"","r_submenu_class":"u-h-spacing-20 u-nav u-unstyled u-v-spacing-10 u-block-cf63-19","r_submenu_item_class":"u-nav-item","r_submenu_link_class":"u-button-style u-nav-link u-white","r_submenu_link_style":"","theme_location":"primary-navigation-1","menuInfo":{"id":"primary-navigation-1","name":"Primary Navigation"},"is_mega_menu":false,"mega_menu":{}} {menu}*

Here is the link from two websites:

Do you know what is the problem?

Thank you
