There is a chain of problems in the workbook you posted. Starting from the top:
1. The Dynamic Filters dialog box doesn't show a filter for Betweenness Centrality, for example, because the first cell in the Betweenness Centrality column is empty. That's NodeXL's somewhat crude way of skipping empty columns -- it just checks the
2. The first cell in the Betweenness Centrality column is empty because the NodeXL, Analysis, Graph Metrics feature didn't fill in that cell.
3. The Graph Metrics feature didn't fill in the first cell, which is for the vertex named unaids.org, but it did fill in the
other cell for unaids.org, which is at row 987. There are two rows for unaids.org, when there should only be one.
So the root cause of the problem is that you have many duplicate rows in the Vertices worksheet. Any idea how that happened?
Regardless, you can fix the problem by copy/pasting the values in the Vertex 1 and Vertex 2 columns on the Edges worksheet to a new NodeXL workbook, then running Graph Metrics again. The Dynamic Filters in the new workbook should then work as expected.
