ADD BILLING INFORMATION on download beta app

Does anyone know why Garmin now gives a popup with the message: "You'll need to add a billing address to your account to complete your purchase. This helps us calculate the proper tax amount for your purchase. Your billing information is only visible to Garmin." when you click the download button to download a beta app to test (and normal app)?

Also the form looks strange BUG?? 

with text like "address.add_modal_title"

and a button to submit like : "address.add_modal_btn"
