Translated only fields that translated in admin panel. All others strings from translated .po and .mo are not translated in UI. Loco plugin can view and edit this but seems like addonify plugin not use it.
I’m also try edit .po in text editor on generate it from https://translate.ww.wp.xz.cn/projects/wp-plugins/addonify-floating-cart/stable/uk/default/?page=10 and put in different places on server – same result.
