In this match (15083796) Le Moing is reserve, but he start titular and play 44 min..
This is a bug
Not necessarily a bug. It depends if you played "let coach decide" or "strictly follow depth chart". Le Moing is better than the guy you set as a starter. So if you played "let coach decide", it is not a big surprise that he played the bulk of the minutes.
