Unfortunately, that is the current state for our survey editor. It’s a known bug. We are updating all of our poll and survey editors to be the same both from a customer perspective and an architectural perspective from the engineering side. It’s been a process for us to unify these codebases, but we hope to be finished soon. It should be a much better and more uniform experience.

Until then, if you are using a survey then setting a correct answer will need to be done at the individual question level instead of the overall survey edit.

Sorry for the trouble! I’ll update this when we have it out
