Well i geuss seing funds doesnt mean they belong to me, only way i see this happen if there was planted in some way addresses or copy of Electrum that looked like electrum that generated someone elses addresses.
I did import same keys before to new electrum wallet and of course i cannot see any of that transactions. However as i mentioned before even new wallet unable to send transactions sign and boradcast are still disabled. Could that be because of the Bitcoin Block chain not fininshed downloading and i need to sign them from Bitcoin core? Or provide some confirmation on core itself. Don't know how this electrum works, if i cannot even send 100% funds that i own and can send from Core.
