Hi there, can't see any of the images you posted so perhaps the transaction IDs can give us more details for someone to help you.
Also, move this to the Electrum section for more help:
https://bitcointalk.org/index.php?board=98.0At a glance, I suspect what happened is you did not disable "change address", so when you made your spend, the remainder of the input used was sent to a change address (still within control of your Electrum wallet). This is likely the output you saw.
To confirm this, simply view all your addresses in address tab>all. You should see that output in one of the addresses there.
