Webinar Registration Settings

[Kirsty1]

Hello

I am hoping that someone can help me. 

I need to change the registration questions for webinars - I have chosen the additional questions I want and then  saved all.  I then tested it but the new questions were not there.  When I went back to the admin section the new questions I had ticked were no longer ticked.  It's as if I cant get them to save.

Has anyone else experienced this and if so did you manage to fix?

Many thanks

Kirsty
