What module are you printing the labels from? If you are printing from Personal Profiles, Contributions, Activities and Skills, the name on the label will be derived from the people in the family that meet the selection.
For example, if you are printing labels from activities and skills for a Sunday school class. The name on the label is derived from the people in the family that are members of that class. So if the husband is still listed as a member of the class, then his name will print on the label. Same thing from contributions, if his profile has the envelope number listed, then his name will be included on the label as well.
