Ionic AOT not injecting AngularFire2 into providers

I’m having an issue with Ionic 3 AOT where the build succeeds, but when I try to serve it, it doesn’t inject an AngularFire2 instance into my services (providers). Works fine JIT, but not AOT. Also, I’m using lazy-loading for my pages.
Here is my Ionic Info:
