Fixing an unsubmitted Citizenship Application Signature for a Minor to use my name instead

[yahadi]

I created Citizenship applications for myself, my wife and two minors.

I signed one of the minors citizenship applications using their name (instead of mine). I did not submit the application yet, just signed it (it's a group application).

How can I fix the signature for the minor to be my name? it does not allow me to edit the signature.
