Why my child is not listed under the dependent care tax break?

It's my year to claim my child as a dependent (her dad and I alternate years, per divorce agreement). My child is already listed as my dependent, but when I go to complete the dependent care part, under "whose care did you pay for", a drop down menu, where I would expect to see my daughter's name, shows nothing. Why is it blank? Daughter is under 13 and obv has no income of her own.
