Divine Bond (Celestial spirit) not working properly for Divine Hunter Paladins

When a Paladin is built as a Divine Hunter and reaches level 5, he gains the Divine Bond feature as would most paladins. Unlike a normal paladin, however, this can only be implemented as a bonus to the paladin's weapon.

The issue I am finding is that to make this work, the developers seem to have implemented this as a new ability called a Celestial Spirit. The part which isn't working is that, even when working with a level 5 character, it shows that the ability cannot be used. See the attached image:

At level 5, it should indicate that I can use the ability once per day and adds a +1 enhancement bonus. I have tested this through 8th level but the enhancement bonus (which should be +2 @ 8th level) remains +0 in the description of the ability.

I tried removing the Divine Hunter feature (from Ultimate Combat), and checked the Divine Bond feature for the paladin of the same level. Interestingly, the Divine Bond feature does not seem to be showing up at all, which I suspect is why this feature isn't calculating properly for my level 5 Divine Hunter Paladin.
