This has a two-factor causation:

1. LemonLib fails to register its capability in the pre-init phase, and
2. Pyrotech fails to register its capability in the pre-init phase.

This created a unique case where both the capability reference for LemonLib and Pyrotech is not injected by the CapabilityManager and both references are null. Then, when LemonLib asks for the capability matching its reference, null, Pyrotech's capability was being returned because its reference was also null, matching, and it happened to be in the list before LemonLib's capability.

The only reason that LemonLib's capability retrieval works is because it is the only capability reference in your entire mod list that is null. When it asks for the capability matching null, its reference is null and it matches. Pyrotech came along and threw a wrench in the mix by not properly registering its capability, subsequently also matching null.

In stand-alone testing of Pyrotech, the null referenced capability worked just fine because, again, it was the only null referenced capability in the mod list.
