Onboard Forms, Signature control - Multiple issues

Hello,

We are seeing multiple errors with signatures on custom forms.

1. When using a previous signature an error displays stating signature cannot be blank.
2. When viewing completed forms the signature field displays combined signatures.
3. When viewing completed forms the signature field displays markings that were not the original signature.

Above issues were seen in both production and stage. LONG (production) and SPG (stage).
