Please help... Child Tax Credit area... Why Turbo Tax only put an X in one of my two boxes??

I have two children that live with me that I'm claimimg.

On my Federal in the Child Tax Credit area it only put an X in one of my two children's tax credit boxes?

But on my AZ State form it put a X in both of my children's tax credit boxes.

Can someone explain why it isn't checking an X in both of my kids boxes on federal??

I'm worried I'm missing out on a tax credit.
