Audio not syncing after export using TB Studio 8

I am having an exporting issue in Toon Boom Studio 8.0. For whatever reason the audio is not syncing up in Quicktime. Within the program, audio playback works fine.

movie setting: 24fps
audio: wav
o/s windows 7

I’ve tried adjusting export settings, reimporting audio, reexporting audio from audacity, using different programs to sync. It’s just not working.

Anyone have any suggestions?
