Issues with language from form locale & PDF language syncing

I have my completed fillable PDF form that I designed in the LiveCycle, but when it's in its PDF version, it's not reflecting "English" as the language setting.

Here's what I've done:

In LiveCycle:

File --> Form Properties --> Defaults --> Form Locale is set to "English USA"

On the same form, in PDF:

File --> Properties --> Advanced --> Language is BLANK & GREYED out so I cannot even edit it.

I'm running LiveCycle 8.2 and Adobe Acrobat 9 Pro.

We can't upload currently because it's not Section 508 compliant with the missing language. I work for the government so there's no workaround - it has to be fixed.

Any advice?
