Macbook Pro 2019 Touchbar acts as function keys even when function isn't pressed (in bootcamp)

My touchbar while in Win 10 bootcamp has been working just fine until today. Now when I press the different touchbar icons it's as if the function key is held down, though the icons don't look like the function keys. For example the dim keyboard backlight button performs as F5, and the other buttons respectively as the other function keys. When I hold the function key, they do change appearance to the correct function keys icons, but they then perform correctly...as function keys. Toggling the function key setting in bootcamp control panel does not fix the issue. Any advice? Restarting the device did not fix the issue.
