Problem:
The pages did not sync correctly from English to Dutch.
Solution:
Check under WPML -> Settings to ensure that the custom fields are not set to "Do not translate." If they are, changing this setting may help the pages to sync properly.

Based on the author, the correct field is the "System Field" _language: https://nootheme.com/forums/topic/translation-of-custom-fields/#post-1221928.
