I'm not sure why each transaction has a duplicate with (0)
Your question is vague so I'm not sure I understood correctly. For your next question please include more detail.
I think you're asking why you're seeing duplicate transaction hashes. There is one row for every token transfer that happened during each transaction. For example, you will see that this transaction includes 4 transfers of the BNB Test token.
I'm sorry for not being more clear. Yes, I was wondering why I'm seeing duplicate transactions and the duplicate has the (0) for the quantity.
I don't know why it has quantity 0. The PancakeSwap contracts are triggering a transfer of 0.
