I do not have WPML installed, and I am also having the same issue.
I’ve been manually exporting fields that I generate using the ACF UI on my local environment, to PHP, and committing that PHP file to the staging site.
I wanted to start using the Local JSON feature to automate this process.
All the JSON files were successfully created when I went through my local UI and clicked “update” for every fieldgroup. But when I committed the new acf-json directory to the staging server (and un-included the php custom fields), no fields were detected by ACF. None at all. But they’re all there in the acf-json directory…
