Hello,

I'm trying to set up some spatial grouping for a site I'm working on, and so far I have three groups: Well Centre, North Area Site, and South Area Site.  All locations of interest have coordinates entered using the appropriate projection (UTM Zone 10N).  I use the MAP tool to select the points I want in, say, North Area Site, then click the "To Filter" button and apply the filter.  Then I move over to the DATA view/page, double check that the filter is applied, and click the "Assign Filtered Locations to a Spatial Group" button at the bottom of the left-hand tool bar.  Then when I clear the filter and return to the map view, I enter SpatialGroups.Spatial_Group_Name =  'North Area Site' into the filter box and apply the filter.  It's at that point that some of the locations that I had just moments before assigned to the North Area Site grouping disappear from view, only to reappear again when I click "Remove Filter".

So my question is: What Gives?  Why are some locations seemingly unable to be added to spatial groups?

Thanks,

Brad Camroux
