Strange thing - each time, when I use sendmany there is one additional transaction which goes from my wallet to my wallet :) Even when I declare just one pair of address:btcAmt and exec sendfrom method in blockchain I can find another abstract transaction - as always, from my wallet to my wallet.
It is happening on os x 10.11. Is it normal? What should I think about it?
Please include exact steps to reproduce and the version you are using.
Are you asking about change? https://bitcoin.org/en/developer-guide#transaction-fees-and-change
I suspect so.

I think @wojciechmorawski is referring to the GUI transaction tab, which may create a separate row for change, but I could not reproduce right now. (Though I am sure I saw it once)
@wojciechmorawski Please clarify or provide further information, I guess we can't help here with the current information...
