I was able to reproduce the issue you're having. It seems that after you have picked a form it doesn't let you set the correct answer(s) and only be stuck on the page shown in the screenshot below.
I have forwarded the issue to our development team so they would be able to look into it. Although we cannot provide you any ETA to when this will be fixed, and we would like to apologize for that, rest assured that once there is an update about it, we will notify you in this thread the soonest.
