I’ve just checked your site in Safari browser and Grid Layout working perfect.
Please see screeshot: http://prntscr.com/77mc6c
The same screenshot form IPad: http://prntscr.com/77mcid
Please update your browser to the latest version and clean all cache.
The screenshot you sent, shows “Featured Products” in correct grid layout, however grid layout for featured products work fine for me also, its the “Recent Products” under that which is out of alignment.
Could you please take one more check, on safari, the “Recent Products”
