Microsoft Teams policy captures non-Teams traffic?

I recently setup SFC to help my wife with her work and I noticed that the “Microsoft Teams” policy seems to consume noticeable bandwidth throughout the day even though she rarely uses that app for video chat.

Is this a known issue? Is it hard for SFC to differentiate Teams traffic from other Microsoft traffic?

I might just not bother given that she uses Zoom for 99% of her video conferencing.
