The check box has become a check box. I don't know what went wrong.

I just want to check that there is no medical history, and the other four items are unchecked

check any of the other four items. No medical history is not selected.
but now that the other four items are singled, the other selected items will also be unchecked.

the environmental background of the problems and what methods you have tried

                }
            }
