This issue has been posted a couple of times, but it still hasn't been fixed. According to Gatherer rulings, Ajani, Nacatl Avenger's 0 ability sets up a delayed trigger that deals damage after token creation. If more than one Cat token is made, such as with Anointed Procession, the rulings state that it is supposed to trigger that many instances of damage, and if a Cat token is not made, such as with Divine Visitation replacing it with an Angel, no damage should be dealt. In the client, however, Ajani only ever does one instance of damage.

"In a case where you create more than one Cat Warrior creature token with Ajani, Nacatl Avenger's second ability (for example, because of the effect of Doubling Season), the reflexive ability will trigger once for each Cat Warrior you made this way. If a replacement effect causes you to create different tokens instead (for example, the effect of Divine Visitation), the creation of those tokens won't cause the reflexive ability to trigger."
