This is only a display issue but does not affect your final submission, so we are obviously looking to get this fixed ASAP.
What currently seems to be happening is that the preview shows the response as if you have selected "No" and this then "sticks" to the Print preview page, even although you may have clearly answered "Yes".
As this is only a Print Preview display problem it does not affect your application that is submitted for review by the councils. You can see this when you look at your submitted application when it appears in your "My Applications" section. This is exactly the same as what the Councils see when reviewing your application.
