Title on shop and product page

Hi
I choose to display globally the title on my site (with Enfold > General Settings Header)
I’ve open a shop in the site, but on certain page like shop, cart product (those pages who were automatically add by WooCommerce), it’s impossible to suppress the title (shop) or make the title disappear (product pages)

If i’m using a CSS or the general settings, the title aren’t ther, but none of the other title of the whole site either.

How can choose not to display title on Woocommerce page with for instance, a remove_action in functions.php or whatever action which not modifiy the parent theme ?

I’ve tried something like

function suppress_title(){
if ( is_category('product') ) {
     remove_action( 'avia_title','avia_header_setting');
   }
}

but whihout any result

Many thanks
