Thank you James.

In your example, the available field names changed (are Data* now) when doing a comparison, while in my example they were named exactly the same as the referenced EventArgument series since I was not doing a comparison.

I am thinking that in my example, the 'MatchingRow' options should not have even displayed, but that would be a design choice in the EdgeFrontier system editor/builder.

For now I suppose I will just ignore the 'MatchingRow' options if I am not comparing Series data to another Series.

Thanks for the helpful screensnips.
