What wrong with ebay's language detection?

I want to leave a polite and positive feedback to the seller as in the photo but ebay didn't allow it. Reason in the photo. What wrong with the engine or my English is not good enough ?

Maybe the five letters starting 'seme*' in 'Advert...'

Revise your comment. Change it to 'description' or 'ad' or 'as advertised'.
