Issues after the last theme update

Hi!

After having updated the theme on my website, I’m experiencing some issues:
– the grid on the linked page appears to be messed up in the Italian version of the page (works properly in the English version)
– on the pages, apart from the home, on the front end, appears a tag on the top right of the page “with-featured-image” > or “without-featured-image” > based on the fact the page as a featured image set or not.

I’ve tried to restore a backup of the site and also to install the theme again, but nothing changes.

Thank you in advance
