Jquery Accordion - 1 accordion tab larger than all others - then fine once another tab is clicked

I implemented the accordion on a WP blog months ago and everything was working fine until recently. On initial page load, one of the accordion tabs is larger than the others - but once another tab is clicked, the tab goes back to it's original size. No css was changed, no JS was changed. It's almost as if it just happened by itself. I have no idea what's going on - I was wondering if anyone has also had this issue. Any help is greatly appreciated! Thank you

Html code is standard - CSS only changed colors and padding:

    <h3><a href="#">Fish Oil Benefits – Why You Need Omega-3</a></h3>
    <div>
        <p>
        What makes fish oil work? Simple. It's the Omega-3.
</p>
<p>Over the last 30 years, what we know about the benefits of fish oil has grown
tremendously. There have been more than 12,000 research papers published on Omega-3
fatty acids.</p>
<p>It’s not surprising that over 100 million Americans now take fish oil supplements. </p>
<p>With OmegaVia, you get a concentrated dose of Omega-3. So you get faster benefits with fewer pills.

<h3><a href="#">Why Pharmaceutical Grade Fish Oil?</a></h3>
    <div>
        <p>
        All fish oils are not the same!</p><p>
<a href="http://www.omegavia.com/what-is-pharmaceutical-grade-fish-oil/">Pharmaceutical grade fish oil</a> supplements are the choice of
doctors, pharmacists and nutritionists.</p><p>
Why? Because it is purer and MUCH more concentrated than regular fish oil.
Regular fish oil has only 30% Omega-3. Which means the other 70% of the oil is, well,
just fat.
</p><p>
OmegaVia is a concentrated dose of pharmaceutical grade fish oil. It has over 80% Omega-3.

<h3><a href="#">The Right Fish Oil Dosage</a></h3>
    <div>
        <p>
        OmegaVia makes <a href="http://www.omegavia.com/fish-oil-dosage/">fish oil dosage</a> easy.
</p><p>Just one pill to get a safe, clinically effective dose.
</p><p>1000 mg Omega-3. That's what the American Heart Association wants you to take
every day. But most Americans get only 100 mg a day. That's just 10%!</p><p>
Remember, 1000 mg of fish oil is not the same as 1000 mg Omega-3. Regular fish oil
pills have about 300 mg of Omega-3 per pill. OmegaVia has 1000 mg of Omega-3 per
pill. This means you have to take 3 to 4 drug store fish oil pills. Or just one OmegaVia.</p><p>
1000 mg Omega-3.  It's what the doctor ordered.  It's what's in one OmegaVia.

<h3><a href="#">Buying the Best Fish Oil</a></h3>
    <div>
        <p>
        Our fish oil is made in Norway using a 5-step purification process. A process
called molecular distillation allows us to produce the best fish oils possible.</p><p>
Unlike other fish oils, OmegaVia oils go through an extra, patented purification step
that removes virtually all of the impurities and odor still left in other fish oils. This
process produces the best pharmaceutical grade fish oil.</p><p>
Our natural enteric coating process improves absorption and also prevents unwanted <a href="http://www.omegavia.com/fish-oil-side-effects/">fish oil side effects</a>.
Each OmegaVia fish oil pill is mercury-free and cholesterol-free. You also get the peace
of mind from independent, third party quality and purity testing.</p><p>
When members of our staff became pregnant, they searched far and wide for fish oil supplements that were safe to take during pregnancy. But they could never get a 'certificate of analysis' proving the purity of the product.</p><p>
Ever since, we made it a company policy to have 100% transparency about what's in OmegaVia. You can inspect our third party Quality & Purity Reports. You never have to worry about Mercury or PCBs.
</p><p>
OmegaVia. Pure. Safe. Effective.
