I can translate a few more things for you

- Credited
These are coins that you have sitting in a wallet, these would have to be withdrawn/manually exchanged.
- Credited for Auto Exchange
These are the coins that you've earned that should be turned into whatever you're exchanging them to(dash in this situation)
- On Exchange
Not sure on this, but my guess would be that these are coins you have in a wallet on the exchange that aren't automatically exchanged.
Apparently there is both an exchange wallet and an account wallet? Not 100% certain as I haven't used MPH yet.
- And the info on the "Transactions" page?
Anything specific? There's a variety of info, some of which should be self explanatory.
