How do you help a member correct a birthdate on a Patriarchal Blessing?

We have a member that has her correct date of birth in her Church membership record, but her date of birth is incorrect in her online copy of her Patriarchal Blessing (in the header information on the left hand side). All the other information in the header is correct, including her member record number. How does she (or how do we help her) correct that field error in her Patriarchal Blessing?

I am sorry if this is covered elsewhere already. I did several google searches restricted to this site, and I've been looking through other resources. I do not see this particular issue covered anywhere.

I'd have the clerk contact GSD and ask.
