Laravel doesnt show validation messages correctly

in my controller i have

public function store(Request $request){
$validator = Validator::make($request->all(), [
"list_img" => "required",
"ge_title" => "required|max:255"
]);
if ($validator->fails()){
return redirect()->back()->withErrors($validator)->withInput();
}

if validation fails i got messages -

validation.required

validation.required .....

instead of

ge_title is required

list_img is required

p.s. I have 3 languages on my site and i dont have validation.php file in resources/lang (if it matters)
