Not removing obstacles dynamically

edit

I'm trying to update the black traces that appear in the RVIZ environment while making changes to the obstacle layers of my robot. While doing this, I also update dynamically via "rqt_reconfigure". While doing this update, when I "disable" the "global_costmap/obstacle_layer" layer, all black traces are removed from the map, and then when I click "enable", the obstacles dynamically move to the correct position. I just couldn't understand why it was like this. Shouldn't this normally be done dynamically? What should I do to make this permanent?
