Either that, or the name Mutatron was "Greekofied" into Mytatron, (Mitatron) and Metatron.
The missing "i" in Metatron may also have been a deliberate move from God who took his name from the name of the old Mitatron (Satan), leaving him with the name Metatron, much like what happened to Adam and Eve; male and female.
In that case Metatron would actually be the name of Satan and Mitatron would be the actual name of Enoch as an angel. Knowledge that may have gone lost in time and lost in translation.
