Adding Traps after connecting Racebox Mini

jglee920

I just added a Racebox Mini to Racechrono and it is connecting. However, I can't add traps, including start/finish, when using Racebox. The options to add traps are grayed out. How do I add start and finish lines specifically?

They should enable once walking a bit, so the bearing (heading) reading comes in.
