How do I add discovery rule for NFS disks to a template

[dthacker]

Zabbix 2.4
What I'm trying to do:
I am using the Template OS Linux to monitor most of my servers. Filesystem discovery is not seeing mounted NFS filesystems for most VM's, which is fine.
However, I have a group of 3 servers where NFS mounts need to be discovered. I've performed these steps so far

• Made a full clone of Template Linux OS
  Created a new Regular Expression containing only NFS as a string to match
  Linked a single VM to the new template
  Attempted to add the new RegEx to the mounted filesystem discovery rules for the template.

I'm following the path Configuration--Templates--->MyTemplateName--Discovery Rules-->Mounted Filesystem Discovery---->Filters to add the additional filter rule. I see a greyed out {#MACRO} and a greyed out "Regular Expression in the entry boxes. I am logged in as admin. Any tips on how to add this filter rule?

TIA,
Dave

After entering the Macro and Regular expression, are you saved by pressing the Update button?

Atsushi, thanks for your question.
The problem occurs when I click on "Add" in the "Filters" box. A new line "B" appears below the original line "A", but the Macro and Regular Expression are greyed out in line "B", and I'm not able to edit them. If I press update, no changes are made.

Here is a screenshot showing the issue.

If I can't add filter data into the new fields, how do I add filter conditions?

TIA

Plase input Label B line, macro and regexp.
