Freeze Quiz Labels

I try to guess at what you want  (English is not your native tongue, I suspect, nor is it mine).

You are not talking about the normal Review mode of quiz slides, where the correct answers and given answers are indicated as checkmarks. I suspect that you want to keep the Correct/Incorrect feedback messages which appear in the first step of the Submit process? There is no longer an easy way to have a Review message on the quiz slides after leaving them.  But that is also not what you want (have a blog explaining how to do that) neither. Do you understand the two-step Submit Process? It is explained in-depth in this blog:

This is the worfklow you could follow:

1. Uncheck both Correct (Success) and Incorrect (Failure) messages in the question slide setup.
2. Create custom feedback messages for both situations, using either captions or shapes as text container. Careful: they will be below the embedded objects on quiz slides, put them in an empty space. Set those messages as 'Invisilbe in Output' by using the eye button in the Properties panel.
3. Use the Success and Last Attempt actions to 'Show....the appropriate custom message'.
4. Since the deletion of the embedded messages have also deleted the first step in the Submit process, where the slide was paused until the learner clicks on the slide or presses Y, the slide is no longer paused! I would propose to add a Next button with a timeline starting after the pausing point of the slide (usual at 1.5secs) and have that Next button pause the slide later than the original pausing point.
5. Once the feedback message 

Sort of a variant of the workflow I explained here:
