Report "All incidents": show sla name

Content

Hello,

 

I want to display the sla name in the report "All incidents".
Therefore I add the column incidents.sla_id to that report. Next step is to add the column sla_instances.sla_id to that report. Now I get 3 join options (attachment: join_options.PNG).
If I choose the first option, I will get an overview of all incident records having a incidents.sla_id not equal to 0, that means all incidents record with  incidents.sla_id = 0 are not displayed.

If I choose the third option, the result is displayed as attachment result.PNG. If a organzation have more than one active sla, there are more than one incident data record of the same íncident id are displayed in that report,
