Preconditions: siteaccess: at least site and fr - I've tested on demo version. Before launching application apply:

php app/console cache:clear -e=prod
php app/console assets:install -e=prod
php app/console assetic:dump -e=prod

1. Log in as admin
2. Go to Page/siteaccess:fr
3. Go to edit mode
4. Add different content to schedule block, for example Places: Valencia, Spain
5. Publish
6. Go to Content/Content structure and click on Edit button for Home CI
7. Click on Preview from right menu bar - "site" looks OK
8. Choose from drop down "fr" - it's shown incomplete. If you go back to site and then choose again "fr" it will look fine.

I've also attached a video.
