Reply to Itch v2.1 - Beatgridding question

I got my Twitch yesterday and tried it out for the first time last evening and loving it so far. I am used to using TP2 for Djing but wanted to try out Itch for the Performance modes.

One thing I have noticed is the auto-beat gridding seems to be off 99% with the Down Beat Marker missing the down beat 99% of the time. Is there any way to manual set the Down Beat Market on the first beat? Any other tips for getting reliable beat grids?
