这是因为在Hedera网络中，一个账户可以有多个公钥，每个公钥都可以进行交易。如果使用不同的公钥查询交易记录，将会返回不同的结果。要解决这个问题，可以通过查询指定公钥的交易历史记录来获得正确的结果。下面提供一个Java代码示例：

import com.hedera.hashgraph.sdk.*;
import io.github.cdimascio.dotenv.Dotenv;

public class GetAccountTransactions {
    public static void main(String[] args) {
        // Load the Hedera network configuration from the .env file
        Dotenv dotenv = Dotenv.load();

        // Grab the account ID and public key from the .env file
        AccountId accountId = AccountId.fromString(dotenv.get("ACCOUNT_ID"));
        Ed25519PublicKey publicKey = Ed25519PublicKey.fromString(dotenv.get("PUBLIC_KEY"));

        // Create the Hedera client and get the account transactions using the specified public key
        Client client = Client.forTestnet();
        AccountRecordsQuery accountRecordsQuery = new AccountRecordsQuery().setAccountId(accountId).setPublicKey(publicKey);
        try {
            AccountRecordsQueryResponse response = accountRecordsQuery.execute(client);
            // Iterate over the transaction records and do something with them
            for (TransactionRecord record : response.getRecords()) {
                // Do something with the transaction record
            }
        } catch (HederaStatusException e) {
            System.out.println("Error getting account transactions: " + e.getMessage());
        } finally {
            client.close();
        }
    }
}
