If all your transactions are confirmed on the blockchain, but your Ethereum (or Ethereum Classic) balance do not reflect the right total amount, with a false or a null sum, it must be a temporary display or server issue.
To see your correct balance:
- refresh your wallet:
click on the circle arrows on the top right corner, near your balance
- and if refreshing doesn't solve your issure:
you can reinstall the Ledger Wallet Chrome application to force it to clear its cache and reload the data from the blockchain
