radiobutton text spreads after scrolling the form

I have some labels and radiobuttons on form

for (int i = 0; i < questionList.Count; i++)
        {
            Controls.Add(questionList[i].GetLabel());
            for (int j = 0; j < questionList[i].RadioButtonCount(); j++)
            {
                Controls.Add(questionList[i].GetRadioButton(j));
            }
        }
        AutoSize = true;

But when I'm trying to scroll content, I have this problem

I would appreciate any help
