Can't preview localized page when using Gatsby Sync

[lisichaviano]

Hi there,
I have been having an issue with Gatsby Preview on DatoCMS, and we have configured two languages (EN and DE). However, for pages that only have content in English, DE (German) appears as the default environment when we are previewing the page.

This happens on all pages, also pages that have content in both languages, but I am just focusing the English content, still the preview shows up with DE as language.

It only happens when clicking the “open preview” button from DatoCMS.
If we access to the preview page from a link, works fine by showing the expected language.

Please, any idea about why is this happening? Thanks in advance.
