Corey, take a look at the lookup_options to specify merge behavior with
APL. Prior to this, APL would not do hash lookups with any merge behavior.
This should change that:
https://docs.puppetlabs.com/puppet/latest/reference/lookup_quick.html#specifying-merge-behavior
and
https://docs.puppetlabs.com/puppet/latest/reference/function.html#merge-behaviors
for the valid options.
