The update just broke returns that have dependent children. It is pulling the information from the dependent list and putting it into the qualifying widower area (Part II, Line 5 of the Federal Information Worksheet) no matter what filing status you are claiming. This seems to happen as soon as you input code L in Part III.

Deleting the information from Line 5 does not work as it will keep populating the information. Nor does deleting and reentering the dependent's information in Part III.
