I did check your form and found that you have selected "require an answer on every row". That means each row needs to be answered. Since you have checkbox "Input Type" selected in matrix field, that is the reason why it allows more than one selection.
I would suggest you to please select "Input Type" of matrix field as "Radio Button" and that should solve your problem. Please check the screenshot below:
Hope this helps.
