You have another plugin (or theme function ?) active that is adding icons to the WP editor. It appears these icons are only added for admins, however the icons are forcefully added on to the 2ns row of icons in the editor.
Most editor altering plugins add a third row of icons to the editor instead of forcing them on to row 2. You'll likely also have problems on narrow screens in the wp-admin editor.
You could see which plugin is responsible for these icons, and point the developer to this thread.
I am not sure which plugin adds the icons. Maybe you can choose layout or select fewer icons in a plugin setting ????
regarding your submit button: try switching the active language to something else and then back to english (Or edit the current language for the submit button). The button shows language variable f_submit
( see classyfrieds->language_edit in your wp-admin panel)
