Quick planner next technical review board saving issue

I enabled the quick planner next technical review in version rtc 6.0.4, everything seems to be ok except for the plan board saving part, I have configured the lanes per iteration that I wanted to see, however I am not sure how can save the lane configuration, every time I navigate out of this section to other areas and returning to the boards, all the lanes go back to unassigned instead of the iteration I assigned to in the beginning.. Is that a known issue in the technical review or am I missing something.
