Hi Kent - Please specify the name of your app.

[Illya Stepanov]

Is the name of app is "Deli"? -- please specify which service name you can't delete?

[Kent Thomp]

Yes, it's name of app is "Deli". All services in service folder can't be deleted. I can't import new database services also.

For more detail, when you click delete a service, it disappear on screen, but'll appear again when I close then reopen the project.
