Reading NTA Charts

Hello, need help reading and understanding NTA charts. Below is for a 40 Mbps MPLS link and I'm trying to figure the top talkers that have consumed the outgoing bandwidth.

From the Top XX Endpoints chart, I see two entries with % utilization. However, one of them is sending and other is a receiver.

I'm kind of lost although we're aware it is the 2nd entry in the chart that is utilizing the most. Just not sure how do I read this in the graph - with the numbers in the chart area and "% utilization" mentioned in parenthesis.
