Removing Correct/Incorrect pop up at the bottom of the Post review feedback layer

Hi everyone, I've been trying to remove/edit the "correct/Incorrect" feedback that we get by default on having a Post-quiz review, but it seems impossible. 

I could edit the Review slide from the feedback master, but the feedback at the bottom still seems to appear. 

Please do let me know, if there is a way to remove/edit that.
