Halo 5 Infection Spawns In Forge?

So I’m having trouble getting my zombies to spawn in on an infection map. I have my spawns set to include during infections and the survivors are all spawning in, just not the alpha zombie. Survivors are red team and zombies are blue. Any ideas?

There is a setting that turns on and off spawn influences. I believe it is called spawn check under respawn. Try that.
