Kansas Resident - Missouri Non-resident: Spouse being taxed on Missouri income tax return

My spouse and I are both residents of KS. I work on the MO side of the KS/MO border. His income is 100% incurred in KS and he has never lived nor worked in MO. The Missouri income ratio summary page shown for my spouse is 0% as it should be. Why is TurboTax showing that there is Missouri income tax due for my spouse's Kansas income? It's essentially doubling the tax amount that I have already paid, resulting in a large amount due to MO. I completed the nonresident return for MO first, then completed the KS return. Is this a bug in the software?

Perhaps this explains it:

"Your Missouri return must begin with your total income (federal adjusted gross income) as reported on your federal return, even if you have income from another state. Your deductions and exemptions apply to your total income, not just part of it. The return is computed as if you are a full year resident and is then reduced by the Missouri income percentage (Form MO-NRI). The result is a prorated Missouri tax, based only on the income earned in Missouri."

Income is automatically pulled in from my federal return, it does not provide an option for editing within the MO return. Then the MO adjusted gross income is split between my spouse and I, the amounts appear to be correct and shows that 100% of my income came from MO and 0% for his, but still shows an amount in the MO income tax column for his income. This is not the first year we've filed a MO return and have not had this issue before. What's the missing link?
