Change the priority of woocommerce_shop_loop_item_title

Hello,
I use the theme oceanwp for my ecommerce website with the plugin Kia subtitle woocommerce bridge.
The subtitles are actually above the product title but i want to have them after the product title:
here is how it appears now
and this is what i want
On the inspector console, when i drop the line of the subtitle under the product title, it is exactly what i want but i don’t know how to do it in wordpress.
I try to change the priority of the subtitle but it doesn’t have any impact.
add_action( 'woocommerce_shop_loop_item_title', 'kia_add_subtitle_to_loop_product', 20 );
is the woocommerce shop loop archive of oceanwp differnt of the default woocommerce shop loop?
I hope my question is clear, sorry for my english
Thank you in advance
