Error with woocommerce shortcode

Hello there
I bought Moesia Pro.
On my homepage, i have services/testimonials/ramdom text+ woocommerce shortcode to display latest offers. Whenever I have more than 2 blocks , the woocommerce does not work. It does not display products. Instead it displays the shortcode itself.
I can’t put the link in here, since this is on “under construction” mode, and the client is watching :wink:
Could you please advise ?
Best, Sonia
