Can you make a test: deactivate wpml for a minute and check if the blog page header shows up ok.
To show the blog page title in stead of just “Blog”, please go to file includes/view/page_header.php and find this line(46): <?php if( is_home() ) $title = esc_attr__('Blog', 'codeless'); ?>
This is a normal page, not portfolio page. Did you use a Visual Composer element to add the blog? You should edit the element options, not the page’s options for this.
Are you referring to this: https://postimg.cc/image/kwpu3udp3/ ?
This is created from a padding set up, probably in your custom css box. But this is present in the home page too.
