Indian Railways — irregularities in waiting list ticket confirmation

I had booked two tickets from lokmanya tilak terminus to katihar junction for 14/10/2018 with pnr no [protected] with current status as wl17 and wl18. When checked on 13/10/2018, it's status was showing rac 22 and rac 23 but after chart preparation, it's status was showing wl 8 and wl 9. Just some time before the actual departure, i am facing a lot of difficulties for my planned journey.
