ACF groups not working correctly?

Good day. I want to say thank you very much for your work and wonderful plugin.
I came across this problem:
My website has a field group that contains 4 text fields. There is also a separate field outside this group. The problem is that it does not see the group, or it does but does not work correctly. since when you save a post, the fields are updated with the same value in all localizations.

Using the available documentation, I tried to register the group in different variations in the wpm-config.json file, but it did not work.

"post_fields": {
        "excerpt":{},
        "test_field": {},
        "404_fields": {
            "title": {},
            "subtitle": {},
            "button_text": {},
            "button_link": {}
        }
}

in this example, he only sees the “test_field”, but not the group.

"post_fields": {
        "excerpt":{},
        "test_field": {},
        "404_fields": {
            "wpm_each": {
                "title": {},
                "subtitle": {},
                "button_text": {},
                "button_link": {}
            }
        }
    }

I also thought that the plugin considers the group to be a kind of array and tried this recording form, but it didn’t work.

Please help me deal with this problem. What am I doing wrong?
