If you have the seed and/or private keys, there shouldn't be problems with wallet recovery. And the derivation path m/44'/0'/0' is also publicly posted on https://walletsrecovery.org/.

You could try to import your seed or private keys into Electrum to get the correct wallet balance. If Electrum displays everything as it should be, you can then clear the cache or re-add your Bitcoin wallets on Jaxx.
