Yes the private keys are definitely wrong.
Without being able to see the wallet file I don't think I can do anything and I don't think it's a good idea for me to get that just in case you have a virus and the virus sends some of the coins to me to make it look like I stole them for example...
If I am sending you a wallet file and left it unencrypted that means my private key is also at risk, so I am not going to do that. But even the file is encrypted, you can still get some idea from it? Also there is no point in giving you free money just to damage your reputation.
Have you encrypted the whole wallet file or added a password to the wallet? If not, then open up the wallet file (it'll probably be in the directory where you launch electrum from in a folder called "electrum_data"). If unencypted it'll list the transactions, addresses and private keys...
I always encrypt the wallet file. I have just created a new wallet with the same seed and leave it unencrypted to check the wallet data, as expected, even after adjusting to 10k addresses limit, none of it has balance in it.
