Problems with eSignature changes in most recent update

Hi everyone,

Historically, when I used to Prepare a Form and I wanted to have a signature field, it would appear as the picture attached. It meant that anyone, including myself, could sign the document, even before it was sent out or before signatures were requested. 

Now, whenever I try to add in a signature field, it looks like a regular Text Field, and I can't actually add a signature to it from my signature bank. This means that there's no option for me to sign my own document. How can I Prepare my Form in such a way as to be able to sign it myself?

Thanks

Paul
