Thank you for contacting WPML support. I'd be happy to assist you on this issue.
Are you referring to options pages as acf options page? To help you further on this issue, I would need further information, so could you please go to WPML > Support > Debug Information and give me the information in the next reply. You can read the detailed instruction here: http://wpml.org/faq/provide-debug-information-faster-support/
Also, can you show me the query example that you are using for default language contents.
I have received feedback from the second-tier team, and this issue has been escalated to our developers. This is not currently supported and will require development work.
