Extra images appearing on product page

Since the update I have an extra image area appearing at the bottom of the page. A div for hikashop_product_image_main appears in the normal place as stated in the display form product->show_default, but another appears also after the html form "hikashop_comment_form", and then is followed by hidden elements hikashop_product_name_N, hikashop_product_code_N .... hikashop_product_id_N.

I do not know why these are appearing. Any help would be greatly appreciated.

These elements are present when you have a product with variants, everything is loaded in the page, and then css properties are applied to display and hide some elements depending on the variants.

I think that your template removed a display: none; property, you can try to add it manually in the css file.
