Dependent information worksheet

I'm getting an error message due to a statement that says "Dependent Information Worksheet: Dependent's SSN should not be the same as the Social Security Number of the qualifying child of Head of Household.  You should only make an entry for a person qualifying you as Head of Household when they are not your dependent.  You will need to delete the duplicate information for either the dependent or the person qualifying you as Head of Household who is not your dependent.

 

I'm confused.  I have two children referenced with two different SSN's.  One I'm claiming and the other my ex is.  So what's the issue as the SSN's are not duplicates after multiple checks?
