Hi,
I checked your site and saw that it due to the language assignment only. For example, a Zentools module called 'Stacked' in 'grid1' position > Menu assignment tab > you assigned to 'Home' page of English but not 'Home' page of Italian so that it doesn't appear now.
I assigned for you and it's showing now, you can apply the same for other modules.
Regards
