Hi, I was hoping a kind soul could help me with a problem. My ledger wallet shows zero in the balance but the most recent transaction is + 0.8 BTC (at 11:23 on the 16/08), which is what it should be as I haven't made any other transactions. That amount was transferred from my Jaxx wallet.

However now the balance is zero. I can see the Jaxx / ledger transaction here at the bottom: https://blockchain.info/address/138ddXRr2rC2hyY9JT8ZKPRpazXHTGXEvM
But there seems to be an additional transaction that hasn't been confirmed, I'm not sure why this here.

Can anyone help explain what it is? I'm a bit of a noob so apologise in advance, I offer gratitude and grateful emoticons to anyone who can help! ☺️☺️
Thanks
Warren
