WAN download/upload speed display reversed

Hi,
when I do speedtest.net, it first download then upload,
but on the traffic graph, WAN traffic seems first upload then download, is it intentional or bug? I just feel the current display is confusing, because I assume the WAN traffic is the overall traffic of my home internet.

The LAN traffic is normal (first download then upload)

This is currently expected, because it’s upload/download from the perspective of the Route10 port, i.e. if your client is downloading, the Route10 is uploading.
