Sorry, your installation is completely outdated. It was released on 18.11.2016, over 4 years ago. Not sure if anyone who helps here in the forum still has such an old installation. From what I understand, the colums for the responses are all the same width and thus are probably defined by the last column "sans response". Rename the column to something like "S" just to see what happens.
And you should seriously consider and update to the latest stable version of Limesurve (which currently is LS 3.x). You are running a software that has not received any updates and bug fixes for 4,5 years and you are possibly collecting personal data. In times of the GDPR this is a dangerous game, in my opinion. If something happens, you can't really argue that you were doing everything in your power to protect the data, by using state of the art software, can you?
