why can't provider paid amount on form 2441 be zero if I used dependent care FSA to pay for all child care expenses?

I used my dependent care FSA to pay for all child care expenses. As a result, on form 2441, turbo tax has zero for amount paid to the provider because it deducts the FSA amount used from the actual expenses. However, in the review stage, turbotax flags this as an issue, saying that the provider amount paid should be greater than zero. But I think I do have to file form 2441 if I used dependent care expenses to pay for child care. How can I fix this?
