Defaulting to expanded

I have version 1.5.2b of this plugin.

The problem is that sometimes the collapsible content defaults to expanded instead of collapsed.

Comparing what what works and doesn’t work I see that the one that doesn’t work has an extra line:

`<span24 id=”swap-id8026″ style=”display:none;”>Close</span24>

Any idea what’s wrong?
