Hi Hemantkumar,
The same seems to be the case if you activate the "Model overview" window and then try to click on the Properties button. Nothing happens.
I guess you could see it as the Properties button applies to the active window. If the active window is "Model overview" or "Attributes", these have no Properties to display. The only window that has Properties to show is the model window, which need to be active before trying to bring up its properties.
