Report Customization

Report Customization

Hello, 
I am a complete newby with Zoho Creator but have managed to start a relational database. Now I have a problem with the 'Report Customisation'. The first view is as it should be with 'Quick View' and 'Detail View' available. But in some Reports they are not visible (2nd pic) and I can't figure out why and how to get them there so that I could edit the 'Quick View'. What does it depend on?
