dynamic obstacle layer not working on global costmap

edit

Hi, I am using the following plugins for global costmap:

plugins:

  - {name: navigation_map, type: "costmap_2d::StaticLayer" }
  - {name: obstacles,  type: "costmap_2d::VoxelLayer" }
  - {name: inflation,  type: "costmap_2d::InflationLayer" }

and in the same way I use these for my local costmap:

plugins:

 - {name: obstacles,  type: "costmap_2d::VoxelLayer" }
 - {name: inflation,  type: "costmap_2d::InflationLayer" }

In this context I have 2 scans (front,back) added to my obstacles observation_sources, dynamic obstacles can be seen in the local costmap but not in the global costmap.

I have no idea what could cause that, since it is working in local costmap most trivial problems can be eliminated.
