Pagination 'Previous' link has active assigned

Hi Have noticed when using page-links with pagination that when on Page 2 the Previous link has the class active added to both the a href and li?

Any idea how to avoid/fix. Odd that it only happens when on Page 2

<perch:if exists="paging">
    <div class="paging">

        <ul class="pagination">

            <perch:if exists="not_first_page">
                <li><a href="<perch:content id="prev_url" type="hidden" encode="false" />"><i class="la la-angle-left"></i></a></li>
            </perch:if>

            <perch:content id="page_links" encode="false" type="hidden" />        

            <perch:if exists="not_last_page">
                <li><a href="<perch:content id="next_url" type="hidden" encode="false" />"><i class="la la-angle-right"></i></a></li>
            </perch:if>

        </ul>

        <p>Pages <perch:content id="current_page" type="hidden" /> of <perch:content id="number_of_pages" type="hidden" /></p>

    </div>
</perch:if>

and page links

<perch:before></perch:before>

    <li class="page-item <perch:if exists="selected">active</perch:if>">
        <perch:if exists="spacer">
            <perch:pages id="page_number" />
        <perch:else />
            <a href="<perch:pages id="url" />">
                <perch:pages id="page_number" />
            </a>
        </perch:if>
    </li> 

<perch:after></perch:after>

Thanks
