When creating a TX you will end up splitting a coin in most cases. Amount you send goes to the target address, remainder will go back to the source wallet, but to another (random?) public address.
Just check the balance with the Chia client abd you will see that you in fact only sent 0.000011
When I recognised coins disappearing to a seemingly foreign address I thought Chia is broken or I was hacked…
From Chia Explorer:
Chia Explorer may show a different net result to your Chia wallet and both are correct. When you send coins, change may go to a different address. The wallet is aware of all your addresses and Chia Explorer is not. You are currently looking at one specific address.
