Your vocal track is an audio file, with its own start and stop. I simply starts playing when BIAB starts.
That is how BIAB records audio which results in exactly what you have described.

I am pretty sure someone will come along shortly and tell you how you can load the vocal track into BIAB so that it can be adjusted to start at a later bar but it will have to be put on a Utility track or a performance track and then you will have to edit it in Audio editor. Which is why most just use their DAW. Good Luck.
