Change: Import Language Override language_code_only Info

Literally to any other value. Right now it only imports language type fields that are provided using the two letter language code. What is provided in your import file is the language field using the language_id. As recently described to chadderuski (basically the original developer of EP4) there is an alignment to be had between what is to be imported and what is allowed to be imported. I changed the plan on mid distribution development. The default setting for that option should have been: language_id_only.
Thank you! This worked. Sorry, I should have poured over the thread more carefully since the solution has already been talked about.

Thanks again for your quick replies and help!
