Security dashboards: Return [ – ] for metrics not being filtered on instead of [ 0 ]

Problem

When users of the security dashboard use filtering, the metrics not included in that filtering return 0. This may mislead users to believe that there are 0 vulnerabilities for a given severity when in fact there are not.

Example:

No filters applied	Critical severity filter applied

Solution:

When filtering is applied show an – en dash in the severity metrics instead of 0

Critical severity filter applied using [–]
