A320 decelerate problem

A few times i had this problem:

When passing the decelerate point on approach engine power is redused correctly. When speed is close to green dot power is then increased again and speed goes almost to 250kts before power reduses again. A bit annoying. Jan are you aware of this?

Did a new flight and it seems that power is reduced 2.5nm before the "D", so autothrust "changes its mind" again and accelerates before this mode kicks back in and works ok for the rest of the approach. Not a big issue
