I'm experiencing the same issue.
I've entered my income as Foreign Earned Income, but chosen NOT to take the Foreign Earned Income Exclusion.
I've then gone to the Foreign Taxes paid section, followed through the interview to the section where I can enter the amount of tax I paid. When I click "done" in the section, my "taxes due" amount has not changed at all and it is still listed as "0" in the deductions column.
