I'm not native english, but it seems that it was correct: https://www.wordreference.com/definition/questionary

Could you explain this change a bit more, or give some docs about it please?

As a native speaker I have to say I have never heard or seen questionary used before and assumed it was a typo.

I'm no native speaker either, but my dictionary says that "questionary" is rare, more widely used seems to be "questionnaire".
