N14 - move bypass automation, same issue since 12

This happened since N12 ( I owned N12, N14 )
When manually draw the plugin or send bypass line and move the clip, it will make some slope like stair, whether using the mouse or shortcut. Someone on the fourm said using preview function could avoid some issue like this, indeed , less problem, but still unpredictable.

N14 improved, but only stair bug gone away, still expand bypass range, break bypass on/off.

Has anyone experienced this?
