By default in our theme if you have product title in page content then it’s disabled in breadcrumbs. If you want to show title in breadcrumbs (Show product name above the price option is off) then in the page content you have “product information” instead of the product title. Now you have product title twice http://prntscr.com/iyu031 because of your changes.
1) This is the old option. But it was broken in update 4.22 and we fixed it in 4.22.1 update.
2) We have sent you file to your registration email. Please, use it to replace xstore/framework/theme-options.php.
