How to delete a project from the system?

I am unable to delete a project despite of specifying the project name after clicking on the trash icon. I want to delete the project - " characterization of infections" . Please guide me how to delete the project

Deleting a project with many entries can take some time, so please wait until the process is complete before leaving the page.
Even when there are no entries, we are aware that our current process is slow when deleting projects due to the underlying filesystem and we are working on improvements for a future release.

Thank you for your patience.
