This is how your Addresses tab should look like. You can see I have many addresses (this is a testnet wallet) and I funded 2 of them. The balance of each address is shown in front of it with the number of transactions each had.
Your total balance is shown at the bottom left. Mine shows 0 + 0.0011 because the transactions weren't confirmed yet.
The green circle at the bottom right indicates a good connection and fully synced wallet. If you click it you should see the nodes you are connected to, their height and your last block height which should be equal.
You can also go to your History tab and see all the transactions involving your wallet (all your addresses). Double click on any of them to see the details. The green highlighted addresses belong to your wallet.
