How to do your own tuning?

[DeathcorePHCRULEZD00D]

I want to do my first CDLC, but i have problem with tuning. I want to set Drop B and i write "B F# B E G# C#" but toolkit says "All fields are required". I dont know what to do ;c

Do the tuning in EOF first

 

Track - ProGuitar - Set Tuning

 

and when you add the arrangement in the toolkit everything should work out automatically.
