I'm not sure that you 'cloned' your project from TC context menu.
I think you just copied some files in windows explorer. Am I right? This is usual way to reach same error.
Right way to clone project is right click at project node in project explorer. Then select 'Clone Project...'.
But if you used context menu - the error is definitely a bug in TC.
I cloned the project from the right click option available on the Project node in Project Explorer.
After some analysis I observed that ID in testMoniker is not unique for some project elements
<testItem name="GUI Verify" key="{57EAF4A9-099A-44F1-A71C-733A17DF9671}" group="False" enabled="True" testMoniker="{82D9CAD7-4C50-49F9-BE4D-744800446EE5}
Hence it throws an error when I load the project suite as
The following project elements have the same keys:
NOTE - The names of the .mds and .tcLS files in both the projects are unique.
Well, I recommend you to open a support case. If you report this behavior as bug you will help many other testers in future.
