Lardarello,
Do you mean you want a set of questions to generate through to the students LRS devices? I have also download the same flipchart and I used it for individual questions which i typed onto the page and then adjusted the answers on the page also. I did not use the insert>question tab.
If you wanted to Insert>questions into the flipchart so you can press the play button on the toolbar and send these questions out automatically you need to make sure you press apply and then done (after entering each question onto the question manager screen).
I hope this makes some sense.
