PoE 2 - Weapon Set Passives allocation bug

Since I started spending weapon skill points, a weird bug (?) has appeared. So I can spend skill points even though I don't have any available. But these "extra" spent skill points have no effect on the character in the game. In general, on Xbox, switching between weapon skill trees seems unintuitive to me (relative to what I've seen on PC), or I don't quite understand something about the mechanic.

Bumping here, I can't allocate notables with my weapon set 2. I was trying to allocate glancing blows, but nothing happens. I'm able to select every node around it, and have the available points.

glancing blows is a keystone, not a notable. keystones cannot be chosen with weapon set skill points

I was confused about this as well.

Here is how it works:

Say you have 2 Passive Skill Points, and you have 2 Weapon Skill Points.

Here are your options:

Option A:
Spend the Passive Points on the tree. Done, nothing else you can do.

Option B:
Spend the Weapon Points for Weapon Set 1.
Spend the Weapon Points for Weapon Set 2.
Done, nothing else you can do.

Option C:
Spend the Weapon Points for Weapon Set 1.
Spend nothing for Weapon Set 2.
Done, nothing else you can do.

The gain is that you can split points, if you so like.
