Hi Chloe,
just for the next situations like that: Just test it and look what is stored in the database, when you manually submit it. But yes, should be "true" for checked.
"Also, I have a couple of dependent fields in my form which display the field names when I preview the form rather than the label names even though I have edited these."
Maybe save the form again. Maybe build it into a landing page and test the approved page. But this is just what worked for me in the past.
Are you sure you have set them up correct?
Best regards
Steffen
