Add ISO library in XCP-NG

I am trying to set up an iso library on xcp-ng. When i go to add the library i first input the address of my freenas server. In the path field i want to specify a path folder within an NFS mount, the only folders XCP-ng presents are the root folders of the shares. I cannot go to sub directories. I am sure I did this before. Why can I not drill down to a subfolder in a nfs share.

You should have a NFS share for each mount, not navigate to a subdirectory of a NFS share. Also, SMB is supported in XCP-NG as well for ISO.
