How to get custom attributes on listpage?

HI,
i’ve tried to get some property also listed at the overview page, but how?
It only works with “address, phone_number and prica?”

I’ve thought it works if i set the “Object Attribute” to “Add Column on “All Properties” page, but i dosen’t work.

Is there a “little” round up to set it some custom fields to the [property_overview] page?
I need to get some fields like, how many Bedroom, m2, and so on

Regards ??
