I'm not sure that's the intended behavior, but it's not going to work, anyhow.   Remotely, ConnectWise Control, VNC, LogMeIn and other similar products connect you to a console session.   If you then log in via RDP, you won't be able to use that console session. The session gets locked and you sit at a login screen, and if you log in again, you disconnect the RDP session. You shouldn't get a black screen, but you won't be able to do what you want to do, anyhow. That's Windows' behavior - doesn't really have anything to do with Remotely. It would happen no matter which remote control software you use.

There are two sessions to select from console and RDP in Remote window if I can choose the RDP session then Remotely should connect me to RDP session not console. or the RDP is listed only and can not be connected to.

This will happen if the RDP application window is minimized. Otherwise, you should be able to see and control the RDP session.
