Margaret – My first instinct is an inheritance issue. On the test, make sure it’s not inheriting the navigation buttons from the AU level. By default, nothing is inherited at the title level, so in theory, that may not be it. I’m of the KISS method of troubleshooting to rule out the simplest possible solution first.
It could also be the Last test page, as it includes a “done” button that has a process test action. This action is not necessary for randomized tests. The course will automatically process the test on the final question then go to the next page OR the pages you’ve selected on the test behavior ribbon.
