Pay with a like not working on home page

Hello,
We purchased and activated this plugin and would like for it to be visible only on the homepage of our site.
However, when we tried using the shortcode all of our hidden content is shown, while the like buttons are all missing.
Here is the shortcode we used:
Metti mi piace per ricecere 5€ di sconto sul tuo prossimo acquisto! [pwal id="69549209" description="prova"]Ciao.[/pwal]

Pls let me know if we are doing something incorrectly, thks!

Kind regards
Claudia
