When a catalog item form is accessed some variables for this item are not visible, but only for certain browsers (i.e. the variables show on Chrome but not Internet Explorer).
It's a node specific issue where one node might be experiencing a caching issue that results in this behavior.
Restart the affected node(s).
1) Identify the node the user is currently logged in by either typing in stats.do in the filter navigator or in the URL directly (i.e. instancename.service-now.com/stats.do)

Connected to cluster node: app00000.sjc000.service-now.com:instance_name[node_number]
2) Open an incident in HI with the affected node names/numbers to have a support engineer restarts the affected node(s)
