Xcode 12 Document Tabs - malfunctions only in my project?

Do I am the only person seeing malfunctioning document tabs?

Sometimes, but often enough, the document tabs stop to work correctly:
  • name of the document tab is still the same, but the tab shows content of another file

  • the same file is opened in more document tabs

This is so annoying and frustrating that I had to disable document tabs.
Nobody else has the same troubles? Now is available Xcode 12.4 and this is still persisting bug. At least in my project...
Nope, you're not the only one. Having exactly the same problem and it is incredibly annoying.

I have it too but only after navigation back. Seems like the tab name is changed but not the content.
