Actually, that is normal and expected. I’ll explain:
Nano uses a 2-step transfer process. The sender creates a “send” block on the network with the transfer details (destination account, amount, etc). At this point, the transaction is pending and can be confirmed in a block explorer (ex: nanowat.ch).
When the destination wallet “sees” the incoming transfer block, then it creates a matching “open” (first transaction) or “receive” (later transaction) block. At this point, the wallet total will be updated and the transfer is considered complete.
Obviously a paper wallet can’t do step #2, but that is okay. The transaction can stay in “pending” status for weeks/months/years until you load your paper wallet seed into a live wallet which will complete the transfer.
Just verify that you sent the transfer to the correct destination address and you should be fine.**
