global costmap is rotated compared to the map

Hello there. I use navigation stack to perform autonomous navigation in known map. I got help from this tutorial http://wiki.ros.org/navigation/Tutori... but, as you can see in the picture below, global costmap is rotated compared to the map. The degrees are not fixed, other times it's 90 degrees, other times 180, or ~40 compared to the map. Everything else (goal pose, local path, global path) is working right according to generated costmaps. Any thoughts?

Out of curiosity, which simulator is this on the right screen?

V-REP. It's easy to use and has a ROS wrapper.

I just figured out I should push the button "2D Pose Estimate" in RViz. But how can we perform SLAM ("Synchronous" Localization and Mapping) if we should give the initial position of the robot in the room?
