multi delay trouble in h4 and h5

trouble after mixdown mix uses presets halion 4, halion 5 or halion sonic
like dub delay (multi delay 1/4d )after mixdown in project, presets using multi delay
playing wrong and mixdown playing artefacting delay timing, after project restart playing presets ok and mixdown in realtime ok
trouble begin at halion 4.5.3 and halion sonic 1.6.3 and no trouble in halion 4.5.2
only I have this problem?
sorry for bad english
