You are talking about a “Group Field” and not a “Field Group”.

A “Group Field” in all aspects is a repeater field that always has exactly 1 row. Updating a group field would follow the same rules as updating a repeater or a sub field.

This is why trying to update the “sub field” is not working correctly when using update_field().

You need to look at the sections here about working with repeaters and sub fields.

This can be done by providing the entire group field array in the update, for example.

$value = array(
  // nested array for row
  // field key => value pairs
  'field_123456' => 'sub field 1 value',
  'field_654321' => 'sub field 2 value',
  // etc
);
// update the "group field"
update_field('field_000000', $value);
