Laravel select from JSON adding double quotes 2 times

Laravel this query:

DB::table('registries')->where('metas->name', $this->registry_name)->select(['metas->date'])->first();

Returning data like this:

{#1463 ▼
  +"`metas`->'$."date"'": ""2017-01-02""
}

Because of this problem (2x double quotes) there is problem with DataTables package, as result converted to JSON still have 4 double quotes.

If I remove select(['metas->date']) everything fine then...
