Only one field group is assigned and there’s only one simple rule: post_type === 'case', as I mentioned in the previous post. There’s no magic in the code, no custom filters/action, fields are registered with ACF GUI (not with PHP) and stored in the acf-json directory. ACF is the only plugin I use at the moment. So for me it looks like a bug.
I can send you a PM with compressed acf-json directory. Will it be helpfull?
