Cantrips not adding to class spell list, what am I missing?

[Senko]

I'm trying to make a new firebolt cantrip. I used copy (ray of frost), edited the details including a unique id. However when I make a character its not an option to select as a spell in their spellbook. If I go to adjustments and add it to class spell list there its selectable so I feel I need to do something to add it to the class list. Restarting herolab doesn't change anything from what I can see it should work but for some reason its not being added to the classes spell list even though the entry is a direct copy of an existing spell.
