XPS 8930, have two Bluetooth adapters

I was experimenting with using my Android phone for internet access from my XPS 8930. After fighting through driver issues (NDIS network driver) and getting everything working (USB, Bluetooth, and WiFi) I was cleaning up. After re-booting I was alerted to a "driver problem" which led me to finding two Bluetooth adapters in Device Manger. I disabled one and have everything running properly. Where did the second device come from?

Note that I appear to have both a BCM20702 and a QCA9377. What is or has gone on here?

Thank you.
