Innate Spells - Bug or user error?

[Micco]

I am trying to add an Innate Spell as a Permanent Added Ability. I can add "Innate Spells" using the list of potential abilities. When I click on the created selection window it shows as having 0/1 Cantrips chosen. I can add a cantrip no-problem.

When I try to add another spell they are shown as an invalid choice ('red'). If I add another "Innate Spells" using the list of potential abilities, it does not allow me to add any more Innate Spells, nor can I figure out how to add something at a higher level than a cantrip. Changing the "Effective Level" and the "Number of Copies" appears to have no effect and not be a saved choice when I reopen the ability.

The creature I'm building them for is an 11th level PC (bard.)

Has anyone successfully added more than a single cantrip as an Innate Spell? If so, what is the trick?

Before I post this as a bug, I want to make sure the insect isn't sitting between the keyboard and the chair.
