mla_term_list not working with Translate Press

Hi David!
I am opening this new topic for the problem using a translation plugin with mla_term_list.
The code works fine with the page when the language is set to Italian:

<form id="mla-text-form" action="." method="post" class="row">
<table>
<tbody>
<tr>
<td width="25%" valign="top">Categoria / Specie: </td>
<td width="50%">
[mla_term_list taxonomy=attachment_category mla_output=dropdown child_of="400" mla_control_name=main_category  depth=1 mla_item_parameter=current_main_category show_count=false use_filters=true]
[mla_term_list taxonomy=attachment_category mla_output=dropdown include_tree=127 child_of="{+template:({+request:main_category+}|1)+}" mla_control_name=include_category mla_item_parameter=current_include_category show_count=true pad_counts=false hierarchical=true depth=1 use_filters=true]
[mla_term_list taxonomy=attachment_category mla_output=dropdown mla_option_value="{+slug+}" exclude_tree=127 child_of="{+template:({+request:main_category+}|1)+}" mla_control_name=sub_category mla_item_parameter=current_sub_category show_count=true pad_counts=false hierarchical=true depth=0 use_filters=true][mla_term_list taxonomy=attachment_category mla_output=dropdown mla_option_value="{+slug+}" include_tree=127 child_of="{+template:({+request:include_category+}|1)+}" mla_control_name=third_category mla_item_parameter=current_third_category show_count=true pad_counts=false hierarchical=true depth=0 use_filters=true]</td>
<td width="25%" valign="top">
<input id="text-form-submit" name="text_form_submit" type="submit" value="SELECT">
</td>
</tr>
</tbody></table>
</form>
 <br>
[mla_gallery]
attachment_category="{+template:({+request:sub_category+}|{+request:third_category+}|no-term-selected)+}" tax_include_children=false
posts_per_page=25 mla_output="paginate_links,prev_next" orderby=date order=DESC
mla_link_href="{+new_url+}?mla_paginate_current={+new_page+}&main_category={+request:main_category+}&sub_category={+request:sub_category,url+}"
[/mla_gallery]
 
[mla_gallery columns=0 mla_style="responsive" size="thumbnail" attachment_category="{+template:({+request:sub_category+}|{+request:third_category+}|no-term-selected)+}" tax_include_children=false posts_per_page=25 orderby=date order=DESC mla_caption="{+title+} : {+description+}" mla_link_href="/modulo-richiesta-foto/?current_id={+attachment_ID+}" mla_nolink_text=" "]

If you try to change the language (with the dropdown menu on the top right) and you select English or Spanish… when you press the button “Select” the page is refreshed and migrate to the home-page. You can see this using the link I added to this topic.
I don’t know if it depends on the plugin or on the different url of translated pages…
thanks for the infinite patience
