Missing points mighty silverfist cruel Act 3

Hello I have a bug where I m missing my 2 passive points, I killed silverfist 6/7 times and the points/book are still not showing up, I thought maybe it was a visual bug on the map and I had them but it didn t show on the map, but after removing all of my passive points I have 114 and I should have 116 since I m level 92 with all of the unique passive points.
