How to get all out going payments of a specific address

platform: "nodejs"
lib: "xrpl - ^2.5.0"

I'm trying to print out all transactions made by a specific account but its showing 2 transactions even though I only sent one. I understand some what that there is in essence outgoing and incoming transactions.

from my source code what changes are needed to filter the sending account to show all outgoing transactions?
why am I seeing 2 transactions?
do i just need to filter by account? but then how do I differentiate the direction?

thanks,

sedo:

connect
create and fund sender and recipient
submitAndWait for transaction
request "account_tx"

full code:
`
const TESTNET_SERVER = 'wss://s.altnet.rippletest.net:51233'

// Define the network client
const client = new xrpl.Client(TESTNET_SERVER)
await client.connect()

// Derive a wallet from a bip39 Mnemonic - cold address - issuer
const senderWallet = xrpl.Wallet.fromMnemonic(getMnemonic())
await client.fundWallet(senderWallet)

// Derive a wallet from a bip39 Mnemonic - hot address - regular user's address
const recipientWallet = xrpl.Wallet.fromMnemonic(getMnemonic())
await client.fundWallet(recipientWallet)

var result = await transfer(client, senderWallet, recipientWallet)
// Check transaction results -------------------------------------------------
console.log("Transaction result:", result)

 const tx_response = await client.request({
    "command": "account_tx",
    "account": senderWallet.address,
    "validated": true
})
console.log(tx_response)
console.log( '*************************' )
console.log(tx_response.result.transactions)

// Disconnect when done (If you omit this, Node.js won't end the process)
client.disconnect()

output:
