prob with a question overview

It's possible that the difference has something to do with having "Selected" as the Initial State. That may have confused the program; I noticed it didn't actually show the Selected state right away. However, answer 3 had that setting, too, but it didn't behave that way. Perhaps the first answer was somehow corrupted.

In other words, I can't say what the exact cause is for why answer 1 doesn't behave the same way as the other answers...

I did notice this: the Selected states have bold text, while the Hover state has regular text (plus a fill). So items 2-4 are actually appearing as per their states: when they are Selected, the text is bold, but it reverts to regular text when the Hover state is activated. 

In the attached file, all the items act the same: the Hover state and the Selected state use bold text. That means the text will look the same when the user mouses over a selected answer. The Hover state will also add a fill. 

FYI: I also changed the Initial State for answers 1 and 3 back to Normal. There's no need for that. To indicate that a given response is a correct answer, you only need to select it in Slide View (or Form View).
