It messed up a survey I did recently. Lets say I am mapping the town parking spots, and I have a field called Ownership. If the Ownership = Private, it should not show on the map (but I still want to have this data on the map).
If I setup a filter to not show the Ownership is not 'Private', all the Private points will disappear, as well all points with blank Ownership.
Is there a way to hide all Ownership = Private, while keeping the blank ones?
