What I can do is make the question turn off after I answer the next question.
This may change the value to '' - it does on regular fields whenever they hide.
The new beta has a way to hide without using relevant.
I just use pages so only so many per page. I like it.
Hope that helps
You can now try the new visible style now in the new version.
