Those features are designed to be used as forum signature blocks, so the code is given as BBcode. If you really want to have them in your profile, you will need to convert [url=...] to <a href="...">, [img]...[/img] to <img src="..."> and [/url] to </a>
Also, I noticed that you have a slight error in the HTML for your profile - the </a> tag after your first image should be after the third.
