That's odd. This version of the mod is not officially cleared to be used with the Chinese translation but it should theoretically work regardless, albeit with English text.
Maybe you're unsure on how to use the mod. The butterfly only appears when you make a suboptimal decision! It's not there all the time. The log access button is on the character overview screen, click on the hearts in the top left and then the "Log" button should be on the right. That is, unless you've disabled one of them in the settings!
