Hey there,
When you translate a post, all the custom field values are duplicated from one to the other.The gallery field in the english post contains the ID’s of selected images.
When translated, the gallery field in the italian post contains the ID’s of the originally selected images.
The issue here is that the ID’s are pointing to the english images, not the translated language images.This is due to missing logic between ACF and WPML.
For now, you will need to remove the selected images in the gallery field and re-select them. This will ensure that the images selected are of the correct language – that way you can edit the titles correctly
I hope that helps
