Why does Electrum embody seemingly pointless inputs in a transaction?

I need to make a fee of x BTC.

My Electrum pockets exhibits two “output factors” within the Cash tab (with the identical handle). Each of those present an quantity a lot bigger than x BTC.

If go to the Ship tab and begin to make a fee to an handle, then click on “Pay…” after which “Superior”, I can see two inputs, which appear to correspond to the 2 “output factors” within the Cash tab and present the identical quantities. The transaction measurement is 447 bytes. I abandon this transaction.

If I’m going to the Cash tab, proper click on on one of many two “output factors” and select “Spend”, Electrum exhibits a inexperienced banner saying “Coin management energetic”. If I begin to make the identical fee, the “Superior” dialog now solely exhibits one enter and the transaction measurement is 226 bytes.

This seems to be to me as if I could make the identical transaction and incur a smaller price through the use of “coin management”. Am I lacking one thing? Is there a drawback or danger to doing this? I am pondering there have to be, in any other case Electrum would simply do it mechanically.

I might perceive needing two inputs to the transaction if x was greater than the quantity related to every one among my two “output factors”, nevertheless it is not.

Thanks!
