Roon sees Ropieee bridge, but no "enable" button appears

I have just installed Ropieee on RPI4b. It seems to go through the normal steps it’s supposed to. In the end when I go to Settings-Audio I can see the RPI-Bridge, but there is no “Enable” button present so I cannot make it an actual endpoint. Any ideas?
Note: I have USB audio enabled and the USB is connected to the USB input of my TEAC NT-505.

Never Mind–I see now that I have to enable the NT-505, not the RPI endpoint. Sorry for the bother.

It sounds great–and very cool having the album artwork appearing on the RPI 7" display. I will try some cheaper DACs now to see how it works without the NT-505.
