Signature in Contact Form 7

Cannot get a box for a signature in Contact Form 7. I have the addon Contact Form 7 signature Addon. I made the field in my pdf a signature where it should be and I placed the bounding box through Contact Form 7 Signature tag the same size. It doesn’t appear. If I put no limits on the size of the bounding box then I can sign but it is over the complete page and not just the narrow area I want the signature on, but it works. Put rows and cols limits makes it not work.

The page I need help with: [log in to see the link]
