Something weird happened now. In some mysterious way the btc I sent to Electrum got back to where I sent them from... 
I shall try to re-send them to my Electrum wallet again.

Was it not maybe 'pending' and rejected due to a fee that was too low? You can try again but make sure that you include a fee appropriate to the transactions otherwise it might get stuck as 'pending' again, if that was the problem.
I don't know how low is too low? I'm new to this. But now the status says it's been payed but the date says pending and that it's unconfirmed. Perhaps I shall wait a bit?
I've asked it before, if we can have the tx id, we can help you by looking at the transaction... In electrum, right click on the pending, or payed amount in the history tab, copy ID to clipboard, paste it in a post, and we can look at it right away.

Its confirmed now, so it cant be "back". Try closing and reopening electrum to see if it appears now.
