Anim Montage not playing on NPC

This is on the NPC’s blueprint. The first Anim Montage is the animation the NPC should be playing. If I set the animation to Mesh it plays, but it does not seem to want to play an Montage of the animation. The second Anim Montage is the Player Character’s Montage, and that one plays out perfectly. Any idea why the NPC Montage does not want to play?

I have a similar problem where certain montages just don’t play for certain NPCs. The slots are correct but if the NPC is facing the player, the montage node will fire but not play.
