one week ago I was sent a small amount of bitcoin (0.03), the transaction shows in the history as received funds but it doesn't show in my available balance, can anyone help?
If you click cmd+j you get a popup with the wallet data. There you see all transactions. You can also double check the balance with cmd+e for opening the emergency wallet tool, there the balance must match the balance of available+reserved funds. If not the internal wallet is screwed up. You could try to delete the SPV file then (see https://forum.bitsquare.io/t/blockstoreexception-corrupted-spvchain-file/1689). After a resync the wallet should be consistent again. If something was screwed up, better start over with a new data directory (see https://forum.bitsquare.io/t/switching-to-a-new-data-directory/1697).
