Checkbox Mapping issues

Hello,

I am having trouble mapping checkboxes to brevo fields. I tried the following:

1. (Preferred solution) Map a single checkbox field with multiple items in cf7 to a brevo multi select field. The CF7 checkbox items’ text matches the text of the items in the multiple choice field in brevo. Brevo field name is AUDIENCE. CF7 attribute used is your-audience. Result: contact is created but AUDIENCE field is blank not containing any of the selected items.
2. Map a single checkbox field with a single item to a Boolean field in CF7. Brevo field name is AUDIENCE_STARTERS. CF7 attribute used is your-audience_starters. Result: contact is created but AUDIENCE_STARTERS field is blank and not set to true.
3. I tried solution 2 with radio buttons also, but no dice.

The contact form I’m using:

<label> Your Name
    [text* your-name autocomplete:name] </label>

<label> Your Email
    [email* your-email autocomplete:email] </label>

<label> I want insights about
[checkbox your-starters checkbox-885 use_label_element default:1 "Starters"]
[checkbox your-leaders checkbox-886 use_label_element default:1 "Leaders"]

<label> Privacy Policy
[checkbox* checkbox-Acceptprivacypolicy class:contact-form-dark use_label_element "I accept the Privacy Policy"]

[submit "Submit"]

Please can you provide some advice and examples (or other potential solutions) as to how I can map checkboxes to brevo? This is critical for audience segmentation.

I thank you for your help and support.
