I'm using Adobe LiveCycle Designer to create PDF fillable forms for work. I've put in a "document signature field" at the bottom so employees are able to digitally sign. I tested my PDF before sending it out by filling out all the fields, including the signature field by creating a fake name. Now with all the other forms I create that fake signature won't stop coming up, it won't let me delete it and it seems like employees aren't able to sign because I can't get rid of it. How do I delete it?
