SGP Does Not See Switch Device

I installed a Digital Loggers unit in ASCOM that shows up in the ASCOM Profile Explorer but does not show up in the SGP Switches tab (Version I understand there are problems with the driver but just wondering why it doesn’t show up. This is my first use of V4. I just switched to Win10 from Win7 so it will run. It is probably something I’m doing wrong. Can someone set me straight?
