CKEditor messing with my source in a weird way.

I am having issues using the source editor when pasting in a particular bit of code.

<![CDATA[
<ul>
<li>Payment amounts shown do not include taxes or insurance.</li>
</ul>
]]>

When I paste in to CKeditor and save or switch to wysiwyg and back to source, this is what I get back:

<!--[CDATA[
<ul-->
<ul>
<li>
Payment amounts shown do not include taxes or insurance.</li>
<li>
]]&gt;</li>
</ul>


Any clue how I can make it stop doing that?
