Well, that's strange.
The reason I assumed a new seed had been generated was because when I used the original seed to recover my 2nd wallet it made a 3rd wallet with a balance of 0. So I figured Wallet_2 had a different seed.
But I just tried again in a desperate attempt and my balance has been restored. Hmmm.
I suppose from now on I won't use a password, as this seems to be a problem a number of people have encountered. Or would that be a bad idea?
I like Electrum and would like to keep using it, but it seems a little volatile.
I'm a bit confused here...
Can you tell us witch wallets you have in your wallet folder (usually C:\Users\[youruser]\AppData\Roaming\Electrum\wallets)
As far as i can tell now, you have 3 wallets, 2 seeds and one password?
I guess you could try to open them one by one, at least see wich one actually controlls addresses having inputs, and see if their passwords work?
It might be a good start to backup your wallet files, seed phrases and password, and try to find out which of the wallets are actually used, and which ones are empty...
Sorry, re-reading my comment I see it didn't make much sense.
I had my first wallet (wallet_default) which had the seed 'floppy tuna treadmill...' etc. I put BTC into it. A couple hours after setting this up my password stopped being recognized. So I recovered the seed and got wallet_2, with the correct BTC balance.
A week later the password stopped working again so I tried using the same seed again to get a 3rd wallet. But the wallet_3 had 0 balance so I assumed that wallet_2 must have generated a new seed and I would need that to recover it. (Never bothered to check)
But then I tried one more time--again with the original seed-- and the new wallet had the balance of wallet_2. So it didn't have a new seed after all.
Now I'm just not using a password. The password I used previously was the same across all wallets.
