Can't send goal to move_base

I'm using move_base to drive a robot but i'm facing a problem that the move_base/current_goal does not the same as which i send to it

Each time i run the move_base_client node it will result in a different goal but none of them is the same as the goal i want to publish

This is the code i use to publish the goal

#include <ros/ros.h>
#include <move_base_msgs/MoveBaseAction.h>
#include <actionlib/client/simple_action_client.h>

typedef actionlib::SimpleActionClient<move_base_msgs::MoveBaseAction> MoveBaseClient;

int main(int argc, char** argv){
  ros::init(argc, argv, "simple_navigation_goals");

  //tell the action client that we want to spin a thread by default
  MoveBaseClient ac("move_base", true);

  //wait for the action server to come up
    ROS_INFO("Waiting for the move_base action server to come up");
  move_base_msgs::MoveBaseGoal goal;

  //we'll send a goal to the robot to move 1 meter forward
  goal.target_pose.header.frame_id = "map";
  goal.target_pose.header.stamp = ros::Time::now();

  goal.target_pose.pose.position.x =  1.0;
  goal.target_pose.pose.position.y =  1.0;
  goal.target_pose.pose.position.z =  0.0;
  goal.target_pose.pose.orientation.x = 0.0;
  goal.target_pose.pose.orientation.y = 0.0;
  goal.target_pose.pose.orientation.z = 0.0;
  goal.target_pose.pose.orientation.w = 1.0;

  ROS_INFO("Sending goal");


  if(ac.getState() == actionlib::SimpleClientGoalState::SUCCEEDED)
    ROS_INFO("Hooray, the base moved 1 meter forward");
    ROS_INFO("The base failed to move forward 1 meter for some reason");

  return 0;

And this is the result when i echo to move_base/current_goal topic image description

And my rviz screen :

It is possible that the global_frame of global_costmap or local_costmap is not set to "map".

Adding the following to the move_base parameter may solve the problem.

  global_frame: map

  global_frame: map
