Applying layouts adds new placeholder recipient

Hey,

I'm having trouble with the functionality behind saving/applying layouts in the integrated designer iframe.

Here is the flow of what is happening:

1. The REST API is used to creaete a package with one recipient that has role/id "test"

2. A user drags a signature for the "test" recipient onto the document using the designer iframe

3. The user saves this layout as "L1"

4. A second package is created with no recipients

5. The user applies the layout "L1"

6. Here is where the problem occurs. When the layout is applied, Onespan creates a new placeholder recipient with role "test", and adds in the signature for this recipient into the document. 

For our case, it makes much more sense to ignore the "test" signature and recipient since that recipient isn't already in the package. I was wondering if there is a setting to change the "Apply Layout" functionality to work like this?

In addition, it seems that I cannot send this package for signing once the new placeholder recipient gets added to the document. I receive the following error:
{"messageKey":"error.validation.packageActivation.unassignedRole","message":"There is a role with no signer.","code":400,"name":"Validation Error"}

Thanks,
Riccardo
