Storyline 360: Multiple Response Quiz Formatting Shape Issue

Hello,

I have been having this issue with Storyline 360 insofar as I have created a big elearning game, and one slide I am using multiple response template, with Vyond videos running behind it in order to emulate a gameshow kind of feel. On the slide view I format all the boxes so they each appear in the same colour and separate from one another. Unfortunately when I go to preview said slide, the formatting is all different in terms of the correct answers no longer have the colour fill formatting but the incorrect answers do. The correct answers do fill when selected, however due to this issue it is obvious to the learner which answers are right and which are wrong. 

I have wracked my brain trying to fix this but can't seem to work it out, any help would be greatly appreciated.
