Dropdown with custom values (again)

Hello,

I followed the instructions here, but I’m not getting the expected result, or I didn’t fully grasped the pourpose of that guide.

My select tag is as follow:

[select* contact-reason id:select-contact-reason
  "technical-issue|I have a technical issue"
  "sales|I want to conctact sales team"
  "other|I have another question"
]

The html I expected:

<select ...>
<option value="technical-issue">I have a technical issue</option>
<option value="sales">I want to contact sales team</option>
<option value="other">I have another question</option>
</select>

The html I get instead:

<select ...>
<option value="technical-issue">technical-issue</option>
<option value="sales">sales</option>
<option value="other">other</option>
</select>

My objective is to show to the user, for every option, a humanly friendly readable label and for each value a corresponding computer friendly slug of characters.

Using CF7 5.9.4 and WP 6.4.3

Thank you.
