does not work until logged in

I’m flying! I recently discovered that the YITH WooCommerce Wishlist plugin does not display the add button to the list of items https://prnt.sc/s8qCag8GYo3v until I log in to site https://prnt.sc/eN1CR2Lfjr1T. I don’t know if there is a problem without losing my respect. When trying to update the plugin, the button does not appear, and if you are logged in, the button does not match the style of the site, everything is great. Please help me please!
