Using iPhone to control Keynote presentation. Duplicated bulletin points

I have a keynote presentation on my air book which I have been controlling from my iPhone. Most of the presenter notes have bullet points to make it easier to spot paragraphs. I have just been forever to download the latest iteration of Keynote for iPhone and since we then all the bullets are duplicated which creates a confusing appearance. The parent version on my air book is still perfect. It seems like it is the iPhone version upgrade that had caused the problem. Is it possible to get back to the previous version?
