Clang Code Model redirects to a file in another project

I have 2 clones of the same project:

• cpp-projects/project-a-clone1
• cpp-projects/project-a-clone2

I have opened each project in Qt Creator, never at the same time and in 2 different sessions.

When I navigate the code using Ctrl+click I can end up in files of the other project.

The most recent case is:

1. Open cpp-projects/project-a-clone1 in Qt Creator
2. Open cpp-projects/project-a-clone1/myclass.h
3. Ctrl+Click (or F2) on the definition of the constructor MyClass()
4. Qt Creator opens cpp-projects/project-a-clone2/myclass.h and set the cursor to the definition of the class (class MyClass)
5. Qt Creator also shows a warning: "This file is not part of any project. The code model might have issues to parse this file properly."
6. In cpp-projects/project-a-clone2/myclass.h, I Ctrl+Click (or F2) on the definition of the constructor MyClass()
7. Qt Creator opens cpp-projects/project-a-clone2/myclass.cpp and brings me to the definition of the constructor

To summarize, navigation does not work inside the opened project, but works in the project that is not opened.

I noticed this first on a large project on Linux and I was able to reproduce it with a minimal project on Windows. To create it I did:

1. Create "project-a" folder and "project-a/project-a.pro" in Windows explorer.
2. Opened Qt Creator, create and open a new Session
3. Open project-a.pro
4. Add main.cpp and MyClass
5. Close Qt Creator
6. Make a copy of project-a folder named project-a-other
7. Remove project-a.pro.user  from project-a-other
8. Open Qt Creator
9. Create and open a new session
10. Open project-a-other/project-a.pro
11. Use F2 on MyClass => Qt Creator opens project-a/myclass.h instead of project-a-other/myclass.h

See "sample.zip"

When using "Find References to Symbol Under Cursor" the search results will show results from both projects.

On Linux, after I removed from disk one of the 2 projects, when trying to F2 to the definition, Qt Creator gives me an error message box saying that the cpp file from the deleted clone is missing. Even after I restarted my computer. I had to delete the content of ~/.cache/QtProject/QtCreator to make it work.

Notes Also I have experienced issues with the code model on multiples project when pressing F2 or using Ctrl+Click.
Like nothing happening, or Qt Creators navigating to someplace where a function is used instead of where it is defined.
