Unable to spend Weapon Set points

Hello, my Weapon Set points are currently display as "2 (8)" meaning I have 8 points total and 2 to spend. But those 2 points cannot be spent at all. I only just realized it but I think it happened when I was switching weapons while allocating points, and/or replacing Weapon Set points with normal skill points. I hope this is fixable otherwise it would mean my character is bricked from 2 (maybe more in the future ?) passive points, kinda huge

I have same problem, spend 6 out of 10 points of set 1, and now can't do it anymore. I alsow respec some set/normal points.

You are able to spend weapon set points when either:
1. You have skill points available
or
2. One of your weapon sets has less points allocated than the other (for example, if weapon set 1 is at 2(8) and weapon set 2 is at 3(8), you should have a point available to allocate for weapon set 2)
The first number on "2(8)" means you have 2 remaining weapon set points that can be allocated with skill points

It's actually just very confusing. When you get new Weapon Skill points from a quest, you are given 2 normal skill points AND it increases your max amount of Weapon Skill points. When you click on the Weapon Set thing when spending your points you are turning normal points into weapon skill points, you don't have a separate "pool" of Weapon Skill points.

So yeah not a bug but definitely needs a better explanation in game

I haven't been able to allocate weapon points at all on my witch. Is there anything about that?
