When an Admin user in ESG clicks the link to "Create New Project", this link URL is /project/form/create.html, which will use the Acadis code (Controller, jsp, etc) to try to create a project. In Acadis, lat/long and start/end values are required, which are not in ESG. So you must enter irrelevant/unused values to create a project

Also, you are unable to edit a Top Level Dataset (Error that POST is not supported)
