Can't edit a first name

TerryCarlson

I am researching the Hanns Kleinman family. The following link has a child indexed without a first name and editing won't let me fix that. The name should be Joan.

https://www.familysearch.org/ark:/61903/3:1:3Q9M-CSWF-YLZ4?view=index&personArk=%2Fark%3A%2F61903%2F1%3A1%3AQP6Q-13T4&action=view&lang=en&groupId=M9FF-NS5

The entry is the first on the left page.

Thank you, Terry Carslon

For that record, I was able to add a Given Name field and then add "Joan"
