NFS: not compatible with new kubernetes stack

our problem is as following:
We added a new Environment and if we want to add a persistent volume via “Infrastructure Stacks” and we go to “Add from catalog” and search for nfs, the Rancher NFS shows “Not Compatible” it doesn’t show “View Details” like in our default environment.
We already set up the docker-volume-netshare-plugin, which we needed for docker-swarm and we installed on our rancher server, which is running a ubuntu 16.04 and is using docker 17.09
Can anyone help us?
If you need more information, let me know.
