pfSense bridge doubles traffic?

Hardware Hub Networking

I setup a pfSense VM where there is a physical Intel NIC as an interface, and I made a bridge interface so that other VMs can connect to. This Intel NIC is then receiving a spanner output from a switch.

Why is the pfSense graphs showing that the bridge is doubling the Intel NIC spanner input vs. being the same?

Probably copying all traffic to the bridge?

Then wouldn’t it be shown in orange as blue is input and orange output?

I finally got the ingest into a stream tool and will setup targeted pcaps so that i can see if its deplicating soon.
