SYMPTOM:
When the view filter is empty for a report, the 'filter on selections' will place the element into a report filter. However, if the view filter has an existing condition, the same option will place the element into the view filter of the report.
STEPS TO REPRODUCE:



CAUSE:
This is working as designed. 'Filter on selections' adds the condition to the view filter if the report is an OLAP report. However, an OLAP report shouldn't be converted to a standard report as a result of this manipulation, so it will add the condition to the report filter if the report is a standard report.
