I'd like to clarify something, So this address 1 (1AXXCct4QATf2UdX92piw1AA2As8AoZaoM) is from your paper wallet? and the funds from it was moved to Address 2 (1KfTVrLG376B7SYb1bA6NnY7KyK825T72B). But when I saw Address 1 transactions from the block explorers the funds were sent to Address 3 (1LsLpbPNS2w98WnKbQ2MmubkQBWhxbPvrz .
And on this part, It seems that you entered Address 2's private keys to spend the funds and send it to an exchange so it means you have its private keys

Is this address also belongs to a paper wallet?
I entered the private key in the field below the public key of Watch Address, put the exchange address and the amount that I want to send, imagining that the change of the partil spend, should go to the main wallet.
