David. First, you're using tick term correctly as it's used in BIAB and as Matt noted, 120 is the default.

When you open your song using the ACW or using the Stems option, the first bar is set with the first Bar placement followed by the 2nd bar placement. When you use the ACW to create the tempo map of the Master loaded onto the Audio Track, the Stems program will also align and synchronize the other stem tracks to the tempo map. Create a tempo map of the complete imported song.
