can't get user = ${reporter} to work

[Deleted user]

Hello,

Im trying to set up IT Service Desk portal the way it recognizes current user.
The goal is to create "hidden" field that will be populated with Reporter information.

I want to link it to user hardware information stored in Insight.

In the background i have an Insight set up with User object types and Laptop object types.

So I'm creating custom Insight field where i put 

Filter Scope (IQL): objectType = "User"
Filter Issue Scope (IQL): "User" = ${currentReporter}

Problem is it is being populated either with info of all users (if "Multiple" checkbox is checked) or only first user.
${currentReporter}

${reporter}

${currentUser}

All give the same result.
