Yes, I can confirm that ACF is having a hard time loading formatted values in a multi-site field when running during the context of a acf/load_field/name=.

1. Request starts at main site
2. I have a filter such as: add_filter('acf/load_field/name=schools', function($field) {});
3. Inside the closure of this filter, I run switch_to_blog(3) and then get_field('state', 'options');

Where state is a field of type “Select” such as:

ny : New York
fl : Florida

And is configured to return Both (Array). But due to a probable issue with ACF, likely at the values data store, it returns the unformatted value ny only.

What I had to do was a dirty workaround:

// Pre-load the school state value in the "plugins_loaded" context
add_action('plugins_loaded', function() {
  if (!is_not_editing_schools()) {
    return;
  }
  switch_to_blog(3);
  global $school_state;
  $school_state = get_field('state', 'options'); // ['ny' => 'New York'], as expected
});

add_filter('acf/load_field/name=schools', function($field) {
global $school_state;
// Now I have ['ny' => 'New York'] here, while in this context I was only able to get 'ny' out of get_field after switch_to_blog.
});
