Additional icons show up...

I modified the TinyMCE init script for advanced mode as follows, but per the screen shot (attached) there are 2 additional rows of icons that are showing up. I haven't touched anything aside from going to Site Configuration-> Tiny Tiny MCE and editing the script for the advanced mode. Thanks!

tinyMCE.init({
mode : "exact",
file_browser_callback: "imceImageBrowser",
init_instance_callback : "resizeEditorBox",
theme : "advanced",
convert_urls : false,

plugins : "safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",

theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,fontsizeselect,cut,copy,paste,|,bullist,numlist,|,undo,redo,|,link,unlink,|,blockquote,pagebreak,iespell,media,image",

theme_advanced_toolbar_location : "top",
theme_advanced_toolbar_align : "left",
theme_advanced_resizing : true,

extended_valid_elements : "a[name|href|target|title|onclick],img[style|class|src|border=0|alt|title|hspace|vspace|width|height|align|onmouseover|onmouseout|name],hr[class|width|size|noshade],font[face|size|color|style],span[class|align|style]",
template_external_list_url : "example_template_list.js",
content_css: "/path/to/your/sites/stylesheet.css" // change this to suit your site - classes associated with divs (eg div.mystyle) will appear in the style dropdown
});
