"Projects by Memory Usage" is not working in MangaeIQ

The report “Projects by Memory Usage” is returning 0 for all projects for openshift in ManageIQ whereas "Projects by CPU usage " is working fine.

We have deployed a manageiq container with the needed memory and cpu. Created provider definition to connect to openshift. We are able to get CPU usgae but unable to get memory and memory/CPU limits for projects in openshift.

Could you please help me?
