Hello, I have similar problem with thumbnails, but unfortunately I`m not good in wordpress ;)
I have theme where main page shows news, every post is shown as a image (featured image).
In PL version (deafult language) everything works fine, but in EN version featured images don`t show.
I tryed to uncheck media translations and uncheck featured images sync. but still the same problem :(
this is my page : http://aussie-cayenne.cba.pl
Maybe I did something wrong? If you need some more infos about my WP settings, please tell me.
