I generated private keys from 24-word seed + password by
https://iancoleman.io/bip39/
and choose BIP49 derivation path

Second derived address exactly match my address with balance and starts with "3"

I copy corresponding private key and import this private key in Electrum.

And I see zero balance.
In "Recieving address"  i see different address starting with "1FGqV"

So, Electrum imported completely different address.  

Asking for support on issue.
