Problem: The client is using English (EN) as the main language and Bahasa Malaysia (MS) as the secondary language on their website. They have an Advanced Custom Fields (ACF) gallery image on a custom post type (CPT) that displays correctly in English. However, in the Bahasa Malaysia translation, the image IDs are not retrieved, and no images are displayed, even though other text custom fields are shown correctly. Solution: We found out that the issue was caused when the "Duplicate existing media for translated content" in Settings > Media is unchecked. After enabling this setting, the images are showing up correctly again. If the problem persists, it might be due to an outdated solution or a different cause. We highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue is still unresolved, please open a new support ticket with us.
