This thread is resolved. Here is a description of the problem and solution.
Problem: ACFML 1.4 translated options pages not appearing
Solution: Client was using "options" as the custom option name, which was registering the options page with specific post_id value, WPML works properly when the post_id value is not defined or defined to default.
Being so backup your DB and try the steps as mentioned here: https://wpml.org/forums/topic/acf-options-page-field-values-not-able-to-translate/#post-3804405
