Error message when trying to view Classification Threshold Analysis Node results

I get the following error when I try to see the Classification Threshold Analysis Node visual results,

“TypeError: Unable to get property ‘init’ of undefined or null reference

at Global code (Unknown script code:1:17445)”

I’m able to see the results in tabular form but there seems to be a problem when I try to visual the graph in the pop-up window. Anyone know how to fix this? Thanks!
