“Restricted” means the app has been limited by your Android on the amount of data it may transmit/receive as a background app. The app settings assume you’re on a meterd or low-volume data plan, and so they don’t transmit data except when they’re active, or up on your screen.

Their upload/download tallies will still count in your Network accounting. Frankly, your screenshot looks like something I’d expect. Nothing untoward seems to be occurring.

Let those other restricted apps 'run in background" (an app permission) and you’ll see a different picture.
