Yes I did one (1) BTC transaction from my electrum Wallet to my own Coinbase exchange/Vault address. My receiving address on Coinbase is: 3BVy8iSzyFGYSzqngk1tdhYiLCMuucRFZB

In electrum I made sure I had the correct address as recipient and under Send Tab - it s hows that transaction (1) with date, Transfer,. amount and status In there I can see that the BTC address of the recipient is the correct address I put in (mine), status is showing "unpaid".

In the History transaction tab I have suddenly 2 entries (1 for 0.000178 and one for 0.231932) - equaling the total amount I was sending 0.23211.

I did not cancel anything, no bump fees. I hit transfer, it created the invoice piece that is showing unpaid,. but the money is gone. And do I know who or what the 2 addressees where that the tokens were sent to: absolutely not.  I only out in my address.

Unknown addresses that I have no clue where they came from but are showing in the transaction details and highlighted in yellow as "Wallet change":
