Why does the Fico Score Simulator not allow you to choose more than one input?

I would like to choose the option to “Pay Down the Balances on All Your Credit Cards” in addition to “Pay Your Bills on Time”.

However, this is not possible. 

When I select “Simulate best action” from the top, it simulates paying down 90 – 100% of credit card balances over the next 24 months. 

However, I would like to determine the outcome of paying 90 – 100% of my credit card balances over the next month coupled with 6 additional months of on time payments would be. 

Does anyone know how to do this?
