Authorize.net Plugin - Language Strings Issue

[bryanearl]

Joomla 3.8.8
VM 3.2.14

I have everything up and running (live) smoothly and the store is taking orders and processing transactions properly using the standard authorize.net payment plugin.

However, for some reason the language strings are not there for the auth.net plugin:

- The "payment method" on the invoice is just blank.
- When a transaction is completed, on the completion page it shows the payment amount, the order number, the status etc. and all of those are just eh language constants, not the values associated with them.
- It's almost like it can't find the language file.

However, most all other language values throughout the store and site are just fine. Any ideas?
