15 Filters represents 15 attribute fields which are single select picklists, and some of these fields are optional.
Problem arises when an attribute is not selected and has the value "". In this case the filter on the analytics dashboard, returns no results since the comparison is either over 'in' or 'matches'.
See the examples below:
No selection = Nature element ?? When there is no attribute value selected, we expect to see all possible values on the dashboard. Currently we are wondering if there is any reliable workaround or a reasonable solution. Any ideas?
