kineic-devel branch issues

[PhilipAmadasun]

I am having issues with kinetic-devel branch package. When I try to launch median_filter_5_example.launch is:
[ERROR] [1667875380.665928716]: Couldn't find filter of type laser_filters/MultiChannelMedianFilterFloat [ERROR] [1667875381.759529779]: LaserArrayFilter not configured [ERROR] [1667875381.759594557]: Filtering the scan from time 1667875379.815046787 failed.
