[Закрытые] Translation of Single Post Type

Hi,

I have created multiple local landing pages (one for each city), for example: скрытая ссылка, скрытая ссылка, ...
They work perfectly in NL (main language of the site), but I'm not able to translate my page into FR or ENG.
My slug translation is already setup correctly, for example:
FR: скрытая ссылка
ENG: скрытая ссылка

This is what I did in NL:
- Theme Builder > created a Custom Post Type "CPT Home Lokaal"
- I created a new post type slug "regio" and a custom slug "poetsbureau-met-dienstencheques"
- I created in ACF a custom fieldgroup "Locatie - basisgegevens" with 3 fields: city, postal code and municipalities (all text fields)

My CPT Home Lokaal template becomes available in FR and ENG as well, but as soon as I switch my language to FR for example and I start editing the template, the changes are applied across all languages.

I hope you can help me out?

Thanks!

Nico
