Tab Text Not Changing Options

[Tempo]

Hello, first time using this forum, and any forum tbh!!

Im new to HTML. New website and it came with sample copy, which Im changing. The copy includes tabs on one page. Two tabs with different text, however, I noticed today both tabs are displaying the same text, despite the code being different. I have made changes to tab 2, but nothing changes. I have made changes to tab 1, and the changes are shown on tab 1 and 2.

Ive checked the code with other tabs on other pages, and I cant see any differences. The code is as follows;

<a name="services"></a>
<h2>Levels of Service offered</h2>
<ul class="nav nav-tabs" role="tablist" id="servicesTab">
<li role="presentation" class="active"><a href="#full" aria-controls="full" role="tab" data-toggle="tab">Full Management</a></li>
<li role="presentation"><a href="#letting" aria-controls="letting" role="tab" data-toggle="tab">Letting Only</a></li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="full">
<p>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</p>
<p>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.</p>
</div>
<div role="tabpanel" class="tab-pane" id="letting">
<p>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.</p>
<p>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.</p>
</div>

Any help appreciated!! Thank you
