Browser for disk volumes when using Ceph as primary storage

[chunkyen]

Hi, I have sucessfully added ceph as primary storage and have created a few instances with volumes on the ceph storage.
I can see the volume when running rbd --id cloudstack ls.
However, when I try to browse for these volumes from cloudstack ui (infrastructure - primary storage - ceph storage name - browser, all I see is files and folders local to the KVM host. Am I missing something or this is not supposed to work for Ceph primary storage?
Thanks
Edit: Cloudstack version 4.22, Ceph version 1.9.3 squid
