thanks for the amazingly fast reply 
I think, as you said, the way I'm doing it is wrong.
right now, I'm putting 1 activity split into 5 subactivities, and another single activity to get 6. I've also tried 2+2+2 each with 1 activity split into 2 with duration 1. From what I understand, that's not the right way to do it. Instead, I should split into 5 with the first one duration 2. I'll try that and let you know how it goes.
Thanks for the great program.
