I've been trying to follow the Electron/Electrum method for splitting my BSV from BCH, but when I import my private keys into ElectronCash, it only brings in a portion of my coins that I earned while mining in a pool. An original set of BCH that I mined solo much earlier is never imported. Any ideas why this might be or how to import it? I can see it in BitcoinABC client wallet, but have no idea how to split BSV out with that client.
