Post language fallback without changing website language

Hello,
I have a question regarding how Polylang handles posts that are only available in a single language. On our blog, we translate static pages and maintain them separately (Finnish and English), but blog posts are always only available in English and we embed Finnish translation in the same post. We noticed, that opening such posts will always change the website language setting from Finnish to English. Is there a way to disable this feature, so that users who browse the website in Finnish can open such posts without their website changing language completely?

As an example:

1. Open website
2. Set the website language to Finnish
3. Open one of the blog entries at the bottom of the front page
4. Notice how the website completely changes language to English unnecesserily and will not even change back once you navigate away from the post

Thank you!
