Windows 10 Settings-Network & Internet Data Usage not counting correctly on dell precision 7760

Brand new Dell Precision 7760 arrived yesterday with Windows 10 Pro OS. One odd thing that I have not seen before on any other computer is that under Settings -> Network & Internet, the data usage counted on this new Precision doesn't seem to count most data. I downloaded a 600 MB file in the Edge browser and under Data Usage after an hour it said 7 MB used. I reset usage, did the same test, and similar reading off by an order or magnitude.

I installed the google chrome browser, went to testmy.net and did a 100 MB file size download test.  Then I went again to the start menu, settings, network & internet and data usage under ethernet says chrome downloaded 2 MB.

I connected a dell usb-c to ethernet adapter which I got with my XPS and which works normally on that laptop. I repeated the same test with internet connected to this ethernet adapter instead of the precision's built in ethernet, and similar result. Windows reports less than 1/10 of the actual data usage on this precision. My other dell computers report fairly normally... (I'm not sure if they're accurate to the MB, but a 100 MB test incremented by approx 100 MB rather than 2-7 MB on this new precision.)

Kind of a minor issue, but it bothered me that it was off, so I went to update & security -> recovery -> reset this pc and reset which brought me to the windows 10 setup again where I created a new user/password, language selection, etc. Still, the data reporting by windows settings -> network & Internet data usage is reporting about 1/10.

Is there a precision 7760 driver that causes this windows 10 anomaly? 

Has anyone else seen this behavior on this machine?
