Error with Dynamic Filters in Graph Section

Apr 24 at 11:13 PM
Hi all,

Have a customized sheet that I coded by hand. Edges and Verticies. Was using dynamic filtering to get a few visualizations with the graph. However, at some point it stopped working and gave me this error:


An unexpected problem occurred. If it occurs again, please copy the details to the clipboard by typing Ctrl-C, then post the details to


[ArgumentException]: An item with the same key has already been added.

at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)

at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)

at Smrf.NodeXL.ExcelTemplate.DynamicFilterSettings.Open()

at Smrf.NodeXL.ExcelTemplate.DynamicFilterDialog.OnLoad(EventArgs e)


Went through poking at a few things here and there but I can't quite track the error down. Any help?
