Closeness metric disappeared! UNA Toolbar in Rhino 6


I have installed Rhino 6 and the UNA toolbar for Rhino 6 for City Form lab's website but for some reason, the Closeness metric does not show inside the Centrality icon. Earlier whenever the 'Centrality' icon was used for analysis, Reach, Gravity, Straightness, Closeness would come together.

Please help.

Thanks in advance!
