I can't export heap of packages

@Error when trying to export subdeck

Recently, some checks have been added to save users from some common mistakes. One of these checks is to ensure that you don’t accidentally create multiple cards with identical front sides. As the message says: Since the notetype is called ‘⁨Basic (and reversed card)…’, you probably want the front side of the second template to be the same as the back side of the first template, don’t you?

Thanks for your reply, but when I’m creating a new card It’s always make 2 same cards, why ? Named card 1 and card 2
