EOS DevAuthTool environment always set to 'Live'?

I’m having issues getting accounts to login using the DevAuthTool. The first wrong thing i see is that when i start up the DevAuthTool, it says its pointing at the live environment:

my game is configured to use the ‘dev’ environment, so i imagine this mismatch will cause problems. but i can’t find any way to point the DevAuthTool at another environment. any ideas?
