there was a wallet file corruption bug in previous versions. you may have been hit by that. i suggest starting over on a fresh PC. leave your current system untouched for reference purposes. restore from the private keys corresponding to addresses with unspent outputs (coins).
The problem is as mentioned above. I have only select private keys, the Addresses that Electrum made from who knows where,
i should have included a link to the relevant github issue. the wallet file corruption bug results in wallets displaying addresses from a different seed/wallet. it requires you to have generated more than one wallet in a session and for you to have a dodgy drive. for example USB drives are disproportionately effected.
https://github.com/spesmilo/electrum/issues/5082another possibility is that you simply have a watch only wallet. in that case it should say watch only in the title bar and under wallet > information.
It's 100% not watch only.
Drive is normal hard drive which is slow but very stable model. I might of generated Standard wallet previously. But not one after another very fast. It says imported wallet, not watch only or standard.
