Signed form

I created a template, and used it with power autoamte to get sequencial signatures. The first signature was received but as I review the agreement I need to make some changes. Currently, adobe is not allowing me to do so. Is there any way that I can make changes to the data the user input (the info they entered is wrong, I do not want to go through another form).

Also how can I stop the emails I receive from Adobe Sign?
