Hello,
1) You did not translate any string http://prntscr.com/jaq0cy Use either po, mo files or WPML string translator http://prntscr.com/jaq16t to translate all the strings from Frontend, here you can find docs https://wpml.org/documentation/getting-started-guide/string-translation/ . Please, don’t hesitate to check WPML documentation to find out how to use this plugin and translate all the content.
2) To add the language switcher to your top bar go to Appearance > Widgets > http://prntscr.com/japfwv I have added it. Here you can find docs about its options if you want to change something https://wpml.org/documentation/getting-started-guide/language-setup/language-switcher-options/
Regards
