Project explorer shows files in two places

[pde14qro]

in an STM32CubeIDE V1.17.0 project I add folders Application and Application/Src. I add Application/Src to the list of  source locations. I add a couple of new C++ template source files to the Application/Src folder. These compile OK.

But why does the IDE show these files in two places and how can I stop or hide this behaviour?

It looks like CubeIDE finds these files without adding to the list of  source locations. Try to remove it, then press F5 (refresh).

Thanks for suggestion. This does indeed remove the duplicates.

Unfortunately source files in Application/Src then no longer build. Although the right-click commands "Build selected file" and/or "Build project" are still available they do precisely nothing on files that are in a folder that is not in the list of source locations.

In fact if you right-click on such a file and choose "Properties" you find that "Exclude resource from build" is both checked and disabled!
