The new wallet i made only uses imported private keys addresses. But old version of Electrum seems like generated fake ones to receive that dont belong to me. Or at least somehow they look completely not same as on Bitcoin core.


Could it be that someone has planted a lot of fake addresses to my Electrum, so the generated addresses do not belong to private keys? Can the Bitcoin Core public key be different for same wallet's different private keys?
The strange thing is there is like a 100 of receiving addresses a lot of them with 0 transactions. Obviously i do not have so many private keys for so many addresses. All the transactions received is unspent, so i doubt it was stolen. But the problem is i cannot get private keys from any than 5 i originally imported. I tried to find anything about this kind of attack or hack in the past on electrum, but it just doesn't match.

Basically Electrum generated bitcoin receive addresses previously that obviously do not look like Bitcoin Core addresses keys i imported. And no one had access to PC except me, it was offline most of the time. Hard disconnected internet and no wifi cards on it. It just looks like it made up random addresses for receiving with different public keys.
