Not really a bug, but the page to "generate embed code" for a survey is inappropriately labeled as "Test/Survey Results."
Noted! I put in a fix for this, will be in the next release.
Also, incidentally, I have no idea what that area is for so that would be a good thing for you to contribute some documentation to.
Ha! It just generated the embed code for putting a survey into an in-app message or field.
