Installation: pre-configured site: twice the same name and one is not working (ans the other one makeing a lot of errors)

I tried to install a pre-configured site on my current nightly build. There are now twice the same pre-configured sites (cf screenshot). One is not working at all. The other is making exception during installation.

Else:
1) Is it currently really hard to know which is the preconfigured site your are installing. There is no description, no template name, no screenshot. You have to guess on your own what it is.
2) The second screen (cf second screenshot) allows you to choose any other template set. Most of these ones are certainly not compliant at all with the current CND pre-package in the import. Could not we only list "compliant" template sets? If the template set and the underlying chosen CND are only "half compliant" could we then make a clear "warning" to the end-users that some data will be lost during import?
3) the last screen, after import, is still not immediately redirecting to the newly created site. Perhaps due to the exceptions. But there is even no manual "next button". You have to modify manually the url.

Finally, for the beta, it would be great to put in evidence the pre-packaed demo which should be the default value. So it should be listed as option 1 in the list with the right package pre-selected so that the user can only select next, next, next,... as indicated on the first screen of the installation wizard.
