Thanks a lot for reporting this issue. We will figure out how to save the name of the project and display it dynamically but for now you could hardcode it.
Open Login.aspx.cs in your Visual Studio. It is located in Sitefinity folder. After that find the following code in Page_Load:
this.projectName.InnerText = this.Request.ApplicationPath.Trim('/');
It sets the project name on the Login page. You could replace this.Request.ApplicationPath.Trim('/') and hardcode your project name. For the admin interface the change should be in /Sitefinity/Admin/Admin.master.cs. You should change the following part of code in Page_Load:
Hope this helps.
All the best,
