chase event don't work

Hi,
i never haddthis problem but with nuendo 7 modulation event is not chased.
using LASS in kontakt i use modulation for “volume” but each time i press play modulation is “0” although a previous event value is “100”. if playback read this event then all comes to normal.

it’s exactly as if chase event was of but i made sure it’s on.
anyone have this ?
