Range sensor layer not getting cleared in costmap after removal of obstacle

[kamalnath26]

I am using Range sensor for detection of glass in the same robot. I have added range sensor layer in costmap but after obstacle detection, layer formed in costmap but even after removal obstacle the layer is not getting cleared.

the problem i am facing is i have attached as a video. in simulation it clears the costmap in front side where lidar in located. but in real time it does not clears costamp in front also. in back side of robot the costmap is not getting cleared in both simulation and real time. i have attached my params file also for your reference. please help me solve this issue , i have also done rosservice call to clear costmap it is getting cleared in simulation. so now i have wrote a client file to call rosservice to clear costmap it is working good in simulation but i dont have hope it will work real time . i think it may hit obstacles in real time and i need to check that and i dont know is it the proper way to do it. if there any proper way to do it please let me know or if i have made any mistakes while adding plugin also please let me know.
