Resharper's Parameter Information missing

The pic below is the Visual Studio's Intellisense, it works fine.

The pic below is the Resharper's Intellisense, but it doesn't show the method summary(description). 

I've reinstalled Resharper(latest version) but it doesn't work. Here is my Visual Studio's and Resharper's config. This problem troubled me a long period. Anyone could give some help to me, thanks.

Someone post his Resharper's param info pic using my config, seems okay.

I don't know what's wrong with my visual studio and resharper. Looking for help. Thanks
