I'm a new user so maybe I am missing something obvious. After downloading the program I was able to add a few emulators where I could select it from the dropdown list to autofill defaults. But now when I go to add a new emulator, this dropdown list has nothing in it. I deleted everything and started fresh before it happened again. I know it isn't super important but I just don't know if I messed something up or not. I attached a picture of the dropdown. Thanks
