Next to the projectname on top of the page appears a link 'de-select project'. Click this to clean the selection. All configurations that you have saved are still available. You will be redirected to the project overview page.
If the project was successfully created, it will appear on the list under project overview. Please note, per default only the 10 recently added projects are displayed. All other projects are organized in pages which you can select at the bottom of the list. You can also select a larger number of projects to be displayed per page, at the lower right side of the overview.
