ACF group filed value disappear on EDIT page

Hi Support Team,

We have a site which has Spanish (ES) as default language and English (EN) as secondary language. We are posting the data via API. When we post the data in both ES & EN language it works fine. But when we trying to map the translations, the mapping is created but somehow the ES data (mainly the ACF custom fields of type=”Group”) disappear from the EDIT page! We can see it in the Post Meta Inspecter and Database, but not on the EDIT page. Which is strange! Could you please guide us?

Thanks
IMRIEL
