Hi,

Thank for your help. Keep up good work.

ok, thank for your help!

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

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.

Hi Evgene,

Thanks for helpful link. I shared my project with support. Please take a look and help me resolve the problem. Thanks in advance.

Okay, could you please show me the way to share the project with you?

I was unable to import/remove database services due to duplicate collection error(appeared when I viewed the error 500 from developer tool of browser). How can I resolve this problem?
