"Start Download" button display on wizard is disturbing

It look like when you choose packages: CAP, DAM and GRID, the NEXT button move to the top of the page in addition to become a "download button". Here, the download button should be applied on the Spreadsheet module obvioulsy.
But when you click on start download, you have a second screen with a "verified" check:

• could Nuxeo use an non-verified module by default ? you feel it's not very secure / trustable
• the CAP module that was in local is suddenly missing with a null value ...

What's the point to explain where the modules are stored by default when Nuxeo suggests them by default ?
In the later_download screenshot, each module will be download later but I don't know when / where to check.

These steps have to be reviewed to address the issues.

See screenshots attached.
