More detail please see here:
You can try shortcode type and see order of each shortcode.
However maybe don’t have order by random.
However you can set it direct in shortcode code: [haru_video_top layout="default" categories="fashion,game,harutheme,sports,technology,travel,vidio" order_by="rand" order="desc" posts_per_page="5" extra_class="style-sidebar"]
You can see: order_by="rand"
Hope this helps!
