Adding Ability Categories (custom1, custom2, etc)

[Cmushi]

I am using Apotheosis and trying to using ability categories. I noticed that ProgressionCategoryFlag has unused categories (custom2-5) but when I tried to use them, they do not appear in the ability screen.

"$type": "Game.GameData.ClassProgressionTableComponent, Assembly-CSharp",
          "CategoryNames": [
            {
              "Category": "General",
              "DisplayName": 2935
            },
            {
              "Category": "Custom1",
              "DisplayName": 415902000
            }
          ],
          "AbilityPointUnlocks": [
            {
              "Level": 1,
              "CategoryObsolete": "General",
              "Categories": "257",
              "Points": 1,
              "UnlockDescription": 2925
            },
            {
              "Level": 1,
              "CategoryObsolete": "Custom2",
              "Categories": "8",
              "Points": 5,
              "UnlockDescription": 415902001
            }

Am I missing something or are custom2-5 not implemented?

I would like to add that yes, I have assigned abilities to the category.
