Early Access PoE2: Xesht not dropping book for last two points

I have beaten Xesht a number of times now as +5 with all 6 points allocated and he is not dropping the final book for the last 2 points. I have received books from other pinnacle bosses in the last few days. I don't know if this is the right place to report this or ask for help.

Same here, any solution to this?
Thanks!
