There seems to be something wrong

There is no column to separate the scales but the jamais-column seems to replace it.

Hi Joffm, thank you for taking the time to answer me.

Here's the requested files, I hope this is what you were asking for. After trying some things, I found out it may (or may not?) be related to the "Mandatory" option in the "General options" of the question. When I activate it, it does equalize the width of the columns, but the problem is 1. I do not want that column in my scale; 2. Since its taking more place in the table, its causing the rest of the answer choices go out of bound (see the attached image).
