Few days ago we lost all labels (text for each field) for one of our survey. All the fields are there and looks like they work fine. When we look at the build in SurveyGizmo the labels are there, but when we go into build it does not appear. It is like all text labels are not there any more, but we see them in the build.
As far as we know we where not changing anything.
Are you not seeing the labels on the live link? If so does the survey contain any translations? Perhaps you have an incomplete translation for your survey and that is the translation being presented based on the language in your browser…
Hopefully this points you in the right direction
