Got this back from Symantec and in my case it is as described, two resource types, computers and virtual machines in the same filter.
Do these filters have computers and VMs in them? If so, that is 'working as designed' state. When there are multiple types, only the two columns are displayed. If this is the case, about the only work around is to limit the filter to one type, which means needing two filters, one for each type.
This issue has been reported to Symantec Development team. A fix for this issue is scheduled to be provided in a future release.
