The problem of question placement can be avoided. When you move your mouse cursor over the icon for adding a new question, click and hold the left mouse button while dragging the question into your preferred position. Once you have chosen the correct position for the question, simply release the mouse button and your question will be positioned in the chosen slot (drag and drop method). In this case, this new question will be positioned where you would like it to be and not at the end of the questionnaire.
If you simply click on the icon for adding a new question and then instantly release the mouse button, the question will be automatically positioned at the end of the questionnaire.
