Do you have ‘Enable Additional Payment Methods’ checked? or Unchecked? Check the configuration for both and see if that makes a difference in your case.
Do you have multiple Stripe Forms on the same page? If you do, try it with only one form on the page. There’s a known issue that our development team is aware of when there are multiple stripe forms embedded on the same page.
If neither of those work, I’d recommend opening a Support Ticket.
