Document hyperlinks not working on Impress LO 4.4

Using LO 4.4 on Windows 7, I have made a Jeopardy-like Quiz game template, with hyperlinks going to various slides. They Hyperlink buttons work when I am editing, but when I start the slide show only the first and second slide’s hyperlink buttons work.

What can I do to get them working again (hopefully without remaking a template and my five quiz games).
