Customer tracked item not showing up

[3l3phant]

After much hunting around for (and failing to find) a way to add a new Special Ability, I realized I was making things too tough for myself. While I'd love for it show up in the Special Abilities tab, because the ability doesn't have any math-based game mechanics I figured I'd just create a Tracker item and have it Show in Tracked Resource List. The description:

Spellplague
When an opponent misses an attack, you may reflect that attack back at them. After using this ability you may not use it again until after a long rest.

Uniqueness:
Add Once

There's one field:
trkMax 1

And two Tags:
User Tracker
Usage LongRest

Show in Tracked Resource List is checked. Under Base Charges I've got 1. I added the 5e Players Handbook in case it was relying on needing a Source. But I'm not having any luck getting it to show up in Tracked Resources and Abilities (let alone Special Abilities).

If someone can point me in the right direction I'd really, really appreciate it.
