I could be wrong but I think this is being shown as intended. I just did one of those online speed tests and took a screenshot whilst it was uploading.
My computer is uploading data to my access point (bottom row).
My switch is downloading that data from the access point and uploading it to my Route10 (middle row).
My Route10 is downloading that data from the switch and uploading it to the internet (top row).
Hence it looks like the traffic is going in both directions. It’s coming in and going out. Well that’s my understanding of it!
