It does seem a little odd that it displays it under that portion of the tree.
Have you attempted addding the usb-uirt under Media Directors? Below software packages and computing applications there is a section for remotes. I use my USB-UIRT for each MD and have it attached during avwizard. If I forget and do it later I have noticed issues with gamepad and dongle remote button mapping. So according to my system I have 5 these and have to see "some devices on this media director did not start a few times before the system disables it. This was my solution btw to the continual 'added removed devices' reload prompt. I found that when usbuirt is present during the install, I can pull it and the gyr-3101 dongle and use it normally without reloads every 5 minutes. Not sure if your remote has that dongle
