Exporting Project Template

I have used "Export Template" option for the below project.

And converted it in to extension using the below link.

https://msdn.microsoft.com/en-us/library/dd885241.aspx 

As expected, extension was installed successfully and worked without issues. But the installed extension's node structure is not as expected. Installed extension comes under "Javascript" instead of Javascript -> Multi-Device Hybrid App.

Any solution for this?

Thanks in advance.
