Removing a property from a static list

[birdman]

I have converted an active list (based on filters, such as properties) to a static list. Now I'm trying to archive a property from a Contact object that was used in the initial definition of the active list. This is however not possible, as the static list seems to 'refer' to that property. How can I archive this property (Afgeronde Training [old])?

This is the way forward ...
