Re: Replace By Fee (RBF) was not available when I have sent using "coin control"...

I have check the tutorial on how to use RBF in Electrum: https://bitcoinelectrum.com/frequently-asked-questions/#my-bitcoin-transaction-is-not-confirming-what-can-i-do
But i could not find any button, menu entry or a setting like that in my Electrum-btc-x86_64.AppImage on Linux. My app language is not english.
Is it because I have selected outputs on a Coins tab or what to try?

Go to preference, you will see the language check if it is not in English and change it to English but electrum is in English by default setting.
