Sticky Password on macOS

I have told paste NOT to save anything from Sticky Password in the settings pane but when I press the copy button, in Sticky Password, next to the password when I'm loging in on some site, Paste DOES save the password to it's area. The problem may be that I have to use the button in Sticky Password and not ⌘c as usual. This seems to ba a major bug since I told Paste not to store anything from Sticky Password.
