markitup settings issue

Question

Here is my settings in set.js. I basically don't want the H1 - H3 tags, images etc. So I deleted those lines but my markitup text area appears to not like the settings and shows up like following. I am using the textile set with a basic simple skin.

Also, is there a sprited version of the images?

mySettings = {
    previewParserPath:  '', // path to your Textile parser
    onShiftEnter:       {keepDefault:false, replaceWith:'\n\n'},
    markupSet: [
        {name:'Heading 4', key:'4', openWith:'h4(!(([![Class]!]))!). ', placeHolder:'Your title here...' },
        {name:'Heading 5', key:'5', openWith:'h5(!(([![Class]!]))!). ', placeHolder:'Your title here...' },
        {name:'Heading 6', key:'6', openWith:'h6(!(([![Class]!]))!). ', placeHolder:'Your title here...' },
        {name:'Paragraph', key:'P', openWith:'p(!(([![Class]!]))!). '},
        {separator:'---------------' },
        {name:'Bold', key:'B', closeWith:'*', openWith:'*'},
        {name:'Italic', key:'I', closeWith:'_', openWith:'_'},
        {name:'Stroke through', key:'S', closeWith:'-', openWith:'-'},
        {separator:'---------------' },
        {name:'Bulleted list', openWith:'(!(* |!|*)!)'},
        {name:'Numeric list', openWith:'(!(# |!|#)!)'}, 
        {separator:'---------------' },
        {name:'Link', openWith:'"', closeWith:'([![Title]!])":[![Link:!:http://]!]', placeHolder:'Your text to link here...' },
        {separator:'---------------' },
        {name:'Quotes', openWith:'bq(!(([![Class]!]))!). '}
    ]
}
