Feed switching languages

I am experiencing an issue with Product Feed Pro where the feed language changes every time it refreshes. I only want the feed to be generated in one predefined language and not switch randomly.

I am not interested in having multilingual feeds; I just need the feed to consistently stay in the correct language. Could you please advise on how to set the plugin so that it strictly follows the primary site language and does not change upon updates? (I am using WPML)

I would appreciate your guidance on how to resolve this issue.
