It’s not a problem with the field group, it imported and works fine for me.
You say that the fields are marked as “future”, WP does this when you set the publish date at some time in the future, you can’t actually set this yourself. In the database, what is the “post_date” value for the fields marked as “future”? Could it have anything to do with a difference in when WP thinks it is and when the server thinks it is?
