Fixed values for same post translations

I’ve encountered exact same problem. Bad news it is not well supported by WPML…

To be more specific it is supported in a very strange way: syncing values for selected custom metaboxes is supported but only “one way” (from original to translated contents but not the other way round).

So in your city example you will be able only to change coordinates when editing post in original language eg. English, but when you will try to change them when editing translation eg. Spanish nothing will happen (your input gets overwritten by original values after saving).

This problem is better described on WPML support forum: https://wpml.org/forums/topic/post_meta-copy-only-copies-one-way-it-should-be-named-sync-and-just-sync/

Unfortunately support response to that issue is rather “negative”. They don’t promise to fix it and claim that is regular WPML behaviour, not a bug.

It is also worth mentioning that all this “one way” sync is only available if you have Multilingual CMS version (for $79).
