Hi @nytrm
Sorry mate, I don’t understand what the issue is.
I can see your previuosly attached image shows all custom fields in the wp_postmeta and you are able to select translations for them.
You say:
“with new fields created the field name is replaced with the field key.”
ACF saves it’s values with the field name (features_link), the field key will look something like field_123567 but this is not to be translated
Your image does show sub field items:
features_links_1_features…
