How to claim VITA on ioPay

Hi,

Brand new to IoPay, and still learning the staking principle.
Staking works fine, however I have a question about the ‘Claim VITA’ part.
I have a HW wallet connected to IoPay and when I see the procedure to claim VITA, I would need to create a new IoTeX address. (link)

Why can’t I just use the ‘claim’ button for the VITA adress that is shown in my ioPay app?

Kind regards,
