Attempting To Populate This Field at Stripe

Hey everybody. I can’t seem to find any documentation on this one column here. I’m trying to populate this column with either the customer’s full name and it’s not working. I’ve even tried the meta data which is an option too. Is this something that just doesn’t show in Test Mode anymore?

Here’s the form in preview mode.

And here is the column I’m attempting to populate

I’d even like to populate the Default Source column if I’m able to as well.

Note that I am simply creating a Customer here, not taking any payments. I’ve installed the first script from this page and have been using this for over 9 years now with some updates and this column has never been populated. I’m just wondering if it’s possible or not.

Thanks in advance.
