Exporting audio From FCPX

Can anyone help me with this problem. I'v mixed my stems in Pro Tools and summed them up in one audio file. Import Audio and video as a separate files and everything is fine and dandy in my timeline but when I'v exported (video and audio as a master file) my audio has lost all of the work that I'v done in Pro Tools (lost all of the automation, music and effects go over my dialogue, no ducking) I'v done same thing in Premiere Pro and everything is fine. Since I really prefer FCPX cause I found this software amazing and fast I would appreciate if someone can share some knowledge.
Thanx

Sounds like there is still audio embedded in the video file. Select the video file and in the Inspector deselect audio.
The problem should be audible in the timeline too, though.

Thanx I'll try that, although when I imported video file I'v only imported VIDEO file (Shift 2) and of corse my original video file does have audio (Unwanted audio).
Thanx Anyway
