Automate Chapter Title Headers for English on the Left and non-English on the right.
Hello all,
I have a booklet with the English language on the left side and another language on the right.

I'm wondering how to apply the header chapter title only to the page with the appropriate language.

As you can see above, the non-English header chapter title is applied to both the English and non-English pages.
May I ask how to appropriately only apply the chapter header title to only the left for English and right for non-English.
Here's my master page by the way:

Thank you, and I hope someone can help!
