It is found would view Survey Performance of a Multi Question, Open Text Answers are not being shown in the global/general view, although there are answers.
In below image you can see how there are 4 responses, but the below widget shows just “Open text Question”

In order to view the answers, you would need to click on the bar in the bar graph itself or change the “Questions” dropdown to that particular question.

It be nice to show it in the general view also as things can be viewed in one area, like all the other questions currently. Currently it looks odd when the other questions shows something , but the open text doesn’t.
