Adv Serach: changing CPT changes the page id?

Hello,
I have a span that I wish it to appear only in the homepage, like this:

`<div class=”clearfix geodir-loc-bar-in”>
<div class=”geodir-search”>

<?php if ( is_front_page() ) : ?>
<span class=”example”>example text</span>
<?php endif ?>`

it works ok, but the span disappears when in search filter I select a different CPT from the dropdown. The page id remains the same so I don’t understand :S

Someone could explain me a possible reason for this?

*other solution would be hiding the span on pages that are not the homepage

Thank you!
