Pagination broken

Hi David !

How are you ?

I’m closer than ever to finish the gallery I wanted.
Although I have a last problem that I can’t solve myself.
In fact, the pagination is broken for my gallery and I can’t find why or how to fix it.

Here is my code:

<form id="mla-search-form" action="." method="get">
<div><strong>Mots clés</strong>
[mla_term_list mla_output=checklist use_filters=true taxonomy=attachment_category mla_markup=custom-term-list-checklist parent=1911 exclude_tree=1884,1881,1882,1883,1885 show_count=true mla_option_value="{+slug+}" hierarchical=true ]</div>
<div><strong>Hauteur</strong>
[mla_term_list mla_output=dropdown use_filters=true taxonomy=attachment_category parent=1881 option_all_text="Toutes les hauteurs" option_all_value=all show_count=true mla_option_value={+slug+} mla_control_name=tag2 mla_item_parameter=current_tag2 ]</div>
<div><strong>Longueur</strong>
[mla_term_list mla_output=dropdown use_filters=true taxonomy=attachment_category parent=1882 option_all_text='Toutes les longueurs' option_all_value=all show_count=true mla_option_value={+slug+} mla_control_name=tag3 mla_item_parameter=current_tag3 ]</div>
<div><strong>Profondeur</strong>
[mla_term_list mla_output=dropdown use_filters=true taxonomy=attachment_category parent=1883 option_all_text='Toutes les profondeurs' option_all_value=all show_count=true mla_option_value={+slug+} mla_control_name=tag4 mla_item_parameter=current_tag4 ]</div>
<div><strong>Couleur principale (RAL)</strong>
[mla_term_list mla_output=dropdown use_filters=true taxonomy=attachment_category parent=1884 option_all_text='Toutes les couleurs' option_all_value=all show_count=true mla_option_value={+slug+} mla_control_name=tag5 mla_item_parameter=current_tag5 ]</div>
<div><strong>Référence</strong>
[mla_term_list mla_output=dropdown use_filters=true taxonomy=attachment_category parent=1885 option_all_text='Toutes les références' option_all_value=all show_count=true mla_option_value={+slug+} mla_control_name=tag6 mla_item_parameter=current_tag6]</div>
<input id="reset" class="gold-button" name="reset" type="reset" value="Effacer" />

</form>
<h3>Résultats</h3>
[mla_gallery]
add_filters_to=any
numberposts=15
attachment_category="{+template:({+request:tax_input.attachment_category+})|'www-evp-fr'+}"
tax_operator=AND
mla_markup=custom-gallery
link=download
mla_nolink_text="Aucun résultat ne correpond à vos critères de sélection."
[/mla_gallery]
[mla_gallery add_filters_to=any numberposts=15 attachment_category="{+template:({+request:tax_input.attachment_category+})|'www-evp-fr'+}" mla_output="paginate_links,prev_next"]
<input id="base-image-download" class="gold-button" style="float: right;" type="button" value="Télécharger les images sélectionnées" /><input id="base-image-clear" class="gold-button" style="float: left;" type="button" value="Effacer la sélection" />

When I select multiple filters, pagination is broken and doesn’t reflect the results.
What have I done wrong?

Thanks,
Best regards.
