What is the evidence that Muhammad ibn Ubayd ibn Abī Umayyah al-Ṭanafisī al-Kūfī al-Aḥdab—who passed away in the year 204 AH—belongs to the eleventh generation?

Muhammad ibn Ubayd al-Tanafisi belongs to the ninth layer, not the eleventh. The notion that he is from the eleventh layer is an illusion, either from the memorizer (al-Hafiz) or the printers. This is because he passed away in the year 204 AH, which is the same year Imam Abu Dawud was born. So how could he be from the eleventh or tenth layer, when he is among the teachers of Imam Abu Dawud's teachers?!
