Alignment

Hi

I have problem with Alignment. I setting Alignment on Centre in shortcode generator and I can see that code
[gallery_bank source_type="gallery" id="10" layout_type="thumbnail_layout" alignment="center" lightbox_type="foo_box_free_edition" order_images_by="sort_asc" sort_images_by="sort_order" gallery_title="show" gallery_description="show" thumbnail_title="hide" thumbnail_description="hide" filters="disable" lazy_load="disable" search_box="disable" order_by="disable" columns="6" page_navigation="disable" animation_effects="fadeIn" special_effects="none"][/gallery_bank]
But all photos are still align to left. On mobile site I have one photo align to left and its look bad. Can someone help me with that?
