Check box doesn’t align with question

First of all, I LOVE this quiz. It’s so simple and versatile! One problem… On all the quizzes, not just in the link given, there are some questions that don’t line up with the check box. I can’t find a common denominator for why that would be. I’m using Chrome as a browser when I create the quiz. On my iPhone, it does the same thing but not on the same questions. It’s not a big deal but looks funky and I’ve put a lot of work into this website. Is it a code fix?
