Conflict with Woocommerce/Polylang since last update > translated products disappear

Hi there,
Since last update (not today’s but the one before), the products don’t show no more in the english version of my website, french is the default language. It says “”404 – Sorry! Page you are looking can’t be found””, although the pages exist and reappear when I deactivate Page Builder by SiteOrigin plugin.
Any idea to help me fix this problem ?
Thank you so much for your time, I really hope there will be a quick solution !
Kind regards.

I use :
Wordpress 4.5.3
Woocommerce 2.6.2
Polylang 1.9.3
Hyyan WooCommerce Polylang Integration 0.25
Page Builder by SiteOrigin 2.4.10
