Reply To: Payment method radio button disappears when there's only one payment method

I’ve just checked and found that troubleshooting mode is off indeed. Don’t know why it happens. Can you please login enable troubleshooting mode in Tools > Site Health > Troubleshooting and activate WooCommerce, WPBakery and payment gateway plugin that’s all you need.
As for testing on your development website – are you sure you’ve had only one payment option? This happens only when there’s only one payment method.
