Triggers not responding on click

Sorry, I know this is a pretty poor explanation of the problem.

I have three consecutive Collapseomatic triggers. At one point, the first one was working, but the second and third one were not. They were uncollapsed by default, and were behaving strangely when I collapsed them. Now, it doesn’t seem like they’re working at all. I am using the latest version of Collapseomatic.

You can see the implementation here: http://adaptiva.staging.wpengine.com/careers/

All three triggers have basically identical markup:

[expand title="Digital Marketing Manager" tag="h3" id="job_title"]
<p>...</p>
<p style="text-decoration: underline;">...</p>
<h4>...</h4>
<ul>
    <li>...</li>
    <li>...</li>
    <li>...</li>
    <li>...</li>
</ul>
<h4>...</h4>
<ul>
    <li>...</li>
    <li>...</li>
    <li>...</li>
    <li>...</li>
</ul>
[/expand]
