Parental addressee and salution
"Student Details | 5. Family/Home | <open Contacts record> | 2. relationship Details | Correspondence & Parental Responsibility ARE NOT selected but the Step Parent is still showing in Parental Salutation & Parental Addressee
The result is that letters are being produced & addressed to the step parent as well as the biological parent when letters should be addressed to the biological parent only."
Capita have confirmed they can replicate the problem that if step parents live with biological parents, the addressee and salutations are updated to include the step parent even if they don't have "Parental responsibility" ticked. You can of course manually change the contents of these fields until they mend it.
Keep an eye.
