I re-installed Electrum and some other wallets and imported the original wallet, but I cannot see the correct balance of the wallet.
By that I understand you don't see the correct balance, but you do see some transactions. Otherwise, you should write that you don't see any history at all.
Also, in which wallet you don't see the correct balance? If it's the others, then it's fine, because Electrum has its own standard of mnemonics. Just import it in Electrum and you'll be able to recover the original wallet.
How can I transfer the BTC from the change address to somewhere?
From your Electrum, click on View -> Show Addresses if you haven't done yet. Then, on Addresses, right click on the change address you want to spend from and click “Spend From”.
