Exporting Midi of multiple voices in a staff with dynamic changes between 2 or more voices has significant issues.

Lets say I have a staff line that has 2 voices, the bottom voice is playing at piano and the top voice is playing at mezzo-forte (Utilizing voice1 and voice2). I accomplish this using dynamic markings set to only apply to that specific voice. This works just fine during playback in the editor. However, I've been consistently having an issue whereby exporting the midi of the track, the latest dynamic change will override all dynamics in the instrument. Thus, if there is a 'mezzo forte' set to only apply to a specific voice, it will instead set all notes from that point forward in the instrument as a whole to mezzo forte. This includes notes in another staff if that staff is in the same instrument (such as a piano).
