The language gaffes are not at all surprising. After all, according the US government, 11% of Delaware inhabitants 16 years or older lack basic prose literary skills. Apparently, they managed to employ one of them! See: http://nces.ed.gov/naal/estimates/stateestimates.aspx
By the way, how do you explain the well populated and clearly identified editorial boards, with several US members. Apparently, they have not been put off by the language skills. One must be tolerant of the less privileged employees.
