Docusign IAM webform and template checkboxes

Hi everyone,

I’m using DS IAM with new interface. I am trying to map a Web Form checkbox group to an eSignature envelope template checkbox group but I keep getting this error:

DOCGEN_PROCESSING_FAILURE  
“Checkbox Values can't be blank”

Setup:

Web Form
- API reference name: Checkboxpartenaire
- Options (and API value): Facebook, Instagram, TikTok

Envelope Template
- 3 checkboxes from the same group
- same Data Label: Checkboxpartenaire
- grouped together

However, in the template editor I only see the Data Label field and no place to define the checkbox option values (Facebook / Instagram / TikTok).

How should checkbox group values be configured in the template so they correctly map from the Web Form? In the example below I was even trying to add the API Value directly but there should be an area to provide both checkbox group API value and each checkbox API value no?

Thanks!
