Logitech M535 Bluetooth Mouse not pairing in Boot Camp

I recently purchased a Logitech M535 Bluetooth mouse for my iMac Retina 27-inch (Late 2015). I successfully paired it in OS X and it worked like a charm.

However, when I booted Windows on Boot Camp, I went to the Bluetooth Settings in Windows and it found my mouse. However, as soon as it started pairing, it gave me an error message saying that the device was not found, and as soon as I closed the error box, the mouse disappeared from the device list. Then, it keeps listing unknown devices, and I knew one of them had to be my mouse. I tried all of them, but they all failed to pair.

Is there a Bluetooth driver issue in Boot Camp? If so, when does the next update come out? Until then, I am using the Magic Mouse on Windows (which still works) and the Logitech mouse on OS X.
