the same just happened to me.
now trying to contact the online support to see if they can solve it, cancel the 2nd card request and get the 12 euros back.
i reckon the problem was that we first went to request the physical card.
we had no money so we had to top up the account, which takes us to the pop up menu, but the card request was already done, just waiting for the funds.
after the top up, the app take us again to the physical card request. Because we received no information the previous request (before the top up) was already done, we request the card again, resulting in 2 requests
