Testnet explorer reported transaction fee

I have just started experimenting with Harmony and I deployed a contract on the testnet. Using the testnet explorer, I can see that the transaction fee is equal to the total gas passed along with the contract function call (example: Explorer | Harmony where every call shows the same fee). Is this just a reporting mistake? does the gas field in the transaction mean something different using Harmony? or is leftover gas not being refunded?
