Thanks for reaching out. I'm sorry to hear that you're having an issue with the usage of one device on your network. I'd love to know more about this and I have a few questions:
It is paused according to a schedule. We just noticed it last week, but am unsure how long it has been happening. I notice a number of devices in our house that show upload when they are paused but it is small amounts so I assumed this was just background stuff (pinging servers, etc). However, the Switch is showing dramatic upload and download which insinuates more is going on than just some mild background noise.
