Bookmarking does not work when test questions are randomized

I need bookmarking to work with the course so users will resume back to where they left off in the middle of the test questions.

When Ithe test questions are in normal order, bookmarking works. However, when I set the test to randomize the questions, the bookmarking does not work any more. If I exit out the course from LMS and launch the course again it starts from the first page.

I need the bookmarking to work. I searched the forum with no luck. Please help and provide some advice.
