Rancher-NFS - Version 1.5.3

I ran Rancher for version 1.5.3 and Rancher-NFS and I’m having serious problems like extreme slow access to the “storage” tab and now I can not handle the volumes in the rancher there is some Rancher-NFS limitation with the new versions of the Rancher?

In the “storage” tab also appears several “inactive” volumes that apparently were created alone.

If anyone can help I thank.
