Radio button selection not saved to Google Sheet

I’ve got a simple form with a few text fields and one radio button. The form is linked to a Google Sheet. When I fill out the form, all the submitted data ends up on the Google Sheet, except the radio button selection. Any clues?

Here’s the form:

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

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

<label> Your Phone:
[text* your-phone] </label>

Select your audition slot:
[radio audition_slot use_label_element “Saturday, November 4th, 11 am – 1 pm” “Saturday, November 4th, 2 pm – 4 pm”]

[submit “Send”]
