Reporting and Survey blocks

We use Cornerstone LMS and are trying to test using the new survey block to gather L1 feedback in a more streamlined way. We are running into an issue where only the last submitted response populates in Cornerstone when we look at the report.

So for example, if you put 3 survey questions in (either as individual blocks or in one mega-block), only the last submitted answer shows up in Cornerstone.

Because the surveys report in the same manner as quizzes, and quiz data correctly populates so we can see every answer a learner submits, why are we running into this issue? Has anyone figured out a solution, or is this a bug that can hopefully be fixed down the line?

It's a shame to have a variety of surveys to embed right in our course, but no way to actually collect the data!
