Playing Techniques (Expression maps) not working

As using trial of Dorico I have problem. Basically playing techniques do not trigger correctly, they seem only trigger at first note. Or is there length which is defined when they are being input. For example creating custom expression map for guitar vsti strum up and down and creating 16 sixteen notes, and inserting articulations note by note, only first strum up one is working, and it lasts full bar length, or so, other strum ups or downs are not working? Same kind of behaviour also with Halion Sonic SE.

There is a known bug where playing techniques right at the start of the score don’t play back correctly. This has been fixed for the the next update.
